Challenges of Mixing Methods and Methodologies

Inventory flow management is considered as one of the most critical and costly aspect of supply chain management. The companies are rigorously trying to balance the cost of inventory so that it is able to fulfill customer requirements. Storing to many stocks increases the cost of warehouses and attaches with the capital further it also causes loss to vendors if in any case there is a drop in demand. When there is very less or no inside available in the inventory upstream, downstream retailers, manufacturers and distributors cannot give commitment for huge orders with guaranty apart from that these people will also not be able to deliver proper forecast. Inventory management is usually considered as a very dynamic and flexible system which is very sensitive towards parameters of cost and it is been developing throughout years. It is also termed parlance management because supply chain managements deals with material flow control from the raw materials suppliers at one end and delivery of finished goods to the consumers at the other end. The most of these techniques are usually dependent of scientific principles further it's based on mathematical and theories of probability. The inventory management is responsible for various activities like marketing, purchasing, production and other techniques so that it can balance the conflicting tools (Bhasin , 2016) This system is responsible to provide knowledge to manage the flow of materials in an efficient manner, utilize people and equipment effectively and coordinate internal activities. The well managed inventory flow management demonstrates that the customers receive the goods efficiently in proper time. It further allows the members of the team to match the inventory with consumer's demand .Apart from that it is mandatory to meet the objectives of the system including capacity, profitability and productivity. There is some of the basic inventory terms listed:-Cycle stock-It is the basic amount of material required in order to meet the demands of the customer. Transit Stock-It is the reroute among the locations which carry the stock. Speculative Stock-It is basically the extra amount of raw materials required to meet the high consumer needs. It is different than normal short term demand. Safety Stock- It is the extra amount of stock in excess of the cycle stock which is usually maintaine d to compensate the uncertainties of the growing demand and substitution.It can also be expressed through a fixed amount (Coca Cola Journey , 2017) The inventory stock management has a good match with demand and supply further replenishing the requirement of inventory. Various operations such as transporting, manufacturing and warehousing; all these are responsible to generate imbalances in the system which finally gives rise to inventory management especially in FMCG industries. Errors in predicting the consumer demand generally impact the production of the product been produced in the plant. Apart from that changes related to promotional and seasonal impact the consumer demand for any particular product. Hence in these case shortages of the inventory further generate imbalances in the entire system. For eg:- shortage of labor, shortage of transportation.raw materials shortage and capacity of manufacturing constraints ; these all are generally responsible for inventory shortage and the company in such cases is unable to meet demands of the customers (Cahan, 2003) One of the most important parameter of shortage of inventory is scheduling. There are basically three kinds of scheduling problems in the FMCG industries:-First the schedule can be inadequate, second the schedule is not carried out in a proper manner and third the schedule can be disturbed by unexpected scenarios such as bad conditions of weather or breaking of equipments. The efficient inventory management will be trading off the conflicts of operations and constraints of inventory so that it can aim for an effective compromise that maintains enough inventories to meet customer demand yet covers variation in the forecast (Floyd & Fowler, 2009) Inventory is very crucial and it very much mandatory but there are other expenditures associated with the same; and the expenditures increases with the increase in levels of inventory generally when indirect and direct cost is indulged. The bigger the inventory, the higher is the possibility of loss by damage, obsolescence, aging and theft. A bigger inventory can result into inefficient handling. It is always recommended to spend ample amount of time in re-warehousing, double handling and stock rotating through man-hours which may have be crucial for some other task. It is very common factor in FMCG industries to carry manufacturing cost of 25% out of the total amount of funds allocated for inventories. Sometimes the expenditure allocated for inventories can be used elsewhere according to the latest requirement of the industry. Thus it is important for the operations to carry out enough inventories so that it can be always updated with its stock so that shortage scenarios can be avoi ded (Green, 2011) The principle of inventory management states that the industrial plant has good amount of production flexibility and capacity and enough area for storage. The basic quantity required for scheduling and planning the receipt of ingredients, raw materials and supplies packaging must be taken into consideration when estimating and calculating finished product requirement, certain patterns of demand , seasonal swings and activities related to promotional might need pre production specific SKU's in order to avoid capacity of production at bottlenecks. But whenever there is pre production of goods there might be less capacity of storage in the production area. In these scenarios there is a shifting of inventory to the distributing centers based on estimated demands. One needs to note that if the required facility has much capacity of constraints or an unbalanced infrastructure then it's mandatory for the team of management to modify the basic inventory process principle (Helfat & Martin, 20 14) The FMCG industries basically need to be proactive in nature for product recall. The earlier model of business required traceability from individual stores to distribution centers. The recent survey conducted on approximate 48 industries in FMCG sector states that the primary cause for installing an automated control system and material tracking system is to get real time visibility and accuracy of inventory so that it can efficiently track and trace the system of inventory. Further the report stated that 52 percent of the industries now use bar coded labels so that they can keep a track on their raw materials, goods finished and progress of work. In order to monitor raw materials, finished goods in the current scenario; it is mandatory to avoid accidental shifting of materials. To work in the real ambience the companies require the industry need to instantaneously hold the inventories either on SKU's real time expiration control of inventories .This can prevent the expired inventory allocation from entering the other processes .Hence resulting in downfall in distribution chain (Hutchison & Boxall, 2014) The aim of inventory flow management is to match demand with supply on regular time .There are two main methods to manage the flow of inventory most frequently termed as production push and warehouse pull. Production push is regarded as one of the most traditional technique whereas warehouse pull is the new one. At times the system of pull is much suitable to the requirements of the distribution network and beverage industry as it the exact consumer demand the basis for substituting inventory. But for satisfying the demands of the consumers without further interruption a certain quantity of inventory must be send out of the door. In this case the production pull system works very well. Both distribution and production push works very well (Lislie,   2011) In the inventory management production push process the periodic demand estimation is often converted into the production plan and a production schedule. Further the process of push production is further converted into transportation schedule which allocate the amount for transporting to each and every distribution center based on each forecast. In the production push process, the facilities with respect to the production or other elements involving centralized planning generally control and manage the movement of inventory within its distribution centers and location. The push process is generally introduced in the processes during periods of promotion, when the products are supposed to push out of the production area on assigning basis. In the inventory management warehouse pull process, demand forecast is also responsible for the plan of production and modification in schedule of production   on the basis of inventory substitution taking into account distribution center (Metcalf e, 2002) The system of pull in inventory flow management deals with responding to consumer's demand. Here the consumer is considered as a important factor while deciding the requirement, location and amount of SKU's. The push process generally sends out the materials based on the forecasted demands of the market or blanket allocation. The pull system sends out the materials on the basis of the demands of the distribution centers which are directly dependents on consumer's demand. The pull process works under right time principle so that it can conduct quick and frequent flow of info and goods. The cost cutting is usually maintained by replacing waste such as inventory which stays too long or huge amount of safety stocks. The pull system functions better than pull system as it is able to operate and deal with all the complex scenarios of beverage industry by using the technology at optimal level. The pull system of the inventory management is combined with scheduling of production and planning of resource it facilitates the matching of supplies with the actual customer demands within the supply chain again the reversal of planning information from consumers to suppliers (Randolf, 2009) The FMCG industries are making a drastic change by shifting from push system management to pull system inventory management. At the same time there are various factors involved which will lead to success of pull system in future. On primarily basis the industry should have a general knowledge about the pull system .It employees should have a basic idea on operation and estimation during the entire process (Austin & Seitanidi,   2012.) Secondly it's important for the cross over to have a proper commitment by the team of management and prior support by members in the senior management. Thirdly there should be introduction of performance parameters so that it can be established within the line of objectives in supply chain management .Fourth, all the locations should have timely and accurate info about the demands and quantities of inventory management. Fifth, an accurate estimating and forecasting system should be established and the sales and operation tem should be liable to it equally. Sixth, parameters of operations such as lead times, cycle times, and capacities are often required to understand production, warehousing and transport. Seventh, it is mandatory to have accurate info and good communication to solve the complexity of business by indulging software system and finally transportation is required for scheduling the systems (Finegan, 2001) The main preference of all the employees in the FMCG distribution and manufacturing is to satisfy the demands of the consumer for production. Controlling and monitoring the inventory is done in order to match the consumer's demand by scheduling the transportation and productions in a way which can decrease the usage of resources in a complex and constant balance. In order to manage the shifting of materials throughout the entire distribution centers and processing unit they usually develop the ability to meet the changing demands of business. This is further integrated with right policies, system and production. The management of processes and technology are usually done on the basis industrial practices and further by effective achieving the balance of inventory flow management. This leads to a company's success in today's challenging time. Managing the entire material transportation efficiently throughout the processing tenure and distribution of proper Inventory management is a crucial part of the "Seamless tube "within any respective FMCG company. The common focus of this sector is on customer satisfaction. The main goal of this sector is to produce good quality goods at nominal rates further packaged and delivered according to the latest demands of the consumers. Proper management of the inventory flow management ensures that every customer and supplier has uninterrupted delivery of delicious and fresh products of the FMCG company. This is also regarded as the greatest form of service delivered to customers. The enti re inventory management basically works on this fundamental.

Technical Writing Assignments - Essay Example It begins by outlining the relationship between microwaves and other forms of wave-radiation, such as light and radio, in order to help the reader understand what a microwave is. It then goes on to discuss some of the special properties of microwave radiation versus other kinds of radiation, such as the fact that microwaves travel in straight lines and can impart energy into water particles. Finally, it moves on to discuss exactly how those properties have been turned in to practical applications: because microwaves can go in straight lines, they can bounce off of objects, and use the reflection to determine distance: this is radar. Typically, radars had to rotate, but according to the article, some new radars are structured more like a fly’s eye, pointing at all directions simultaneously. Microwaves also have the property of being able to excite water molecules through other substances, meaning that they can be used to cook food. The article also details the timeline of these discoveries, so that its reader is able to gain a better understanding of the process through which microwaves have been developed throughout time. Fundraising Proposal This proposal will discuss fundraising for public schools. It’s primary audience will be school administrators, with its secondary audience being outside groups including businesses, that could create reciprocal fundraising relationships with schools. Fundraising is a difficult task for a public school. Parents feel that they have already paid their fair share (if not more) through taxes, and are often cash-strapped in a way that makes it difficult for them to put more money towards their children’s education. Furthermore, they will often be donating to projects that will never see fruition in their children’s educational experience. While some things, such as buying new instruments for a music class, can be done relatively quickly, most of the needs that will be addressed by fundraising, such a s redevelopment, renovation, adding new buildings and so forth can only happen after a great deal of fundraising has already occurred, bureaucratic processes have moved forward, and the investment is actually converted into a practical benefit to children. With children being in a school at most six years (for primary students) it is incredibly unlikely that any parental donation. Sure, some families may have several children attend the school, but this is unlikely. For all of these reasons, parents, though often tapped for fundraising efforts in schools, are actually not particularly beneficial. Schools would do better to build fundraising relationships with outside organizations rather than parents: these relationships can be longer lasting, and often involve larger sums that parents would have access to. Furthermore, any relationship should be mutually beneficial, and this is more possible with outside groups than it would be with parents. These forms of fundraising relationships must be reciprocal: this does not mean quid pro quo, where the school does something of equal value specifically for a particular amount of donation – this is fundraising, not anything else. However, it should be beneficial to both parties. These fundraising relationships will obviously be beneficial to the school, which gets money for much needed upgrades, equipment, building projects and so on. But the question remains, how should this relationship be beneficial to

Mans Effect On The Environment Essay -- essays research papers

Man’s Effect on the Environment 1) SOURCES OF POLLUTION Freshwater Environments : Man pollutes freshwater all over the world in many ways there is much waste and pollution that ends up in rivers. One of the main hazards is called eutrophication, this process becomes enriched with artificial nutrients from fertilisers which run off into the rivers and upset the natural nutrient cycle of the river, lake or pond. The water turns green because of the algae which when they die multifly using up all the oxygen.   Ã‚  Ã‚  Ã‚  Ã‚  Similar consequences occur if raw sewage is pumped into a river. Chemical waste from factories dump their un wanted waste into rivers, lakes or ponds as well. One major component that effects the water wildlife is the insecticide DDT which damages animal tissue and is dangerous to humans , this can be passed along the foodchain. Marine Environments : 80% of the waste which is pumped into the sea each year is produced by dredging, 10% is industrial waste and 10% is sewage. Some of the consiquences due to this are :- presence of toxic substances and the rapid uptake of contaminants by marine organisms to name but a few. Oil spillages either by tankers or offshore ridges cause devistating effects on the local environments. Oil is extremely dense which means it floats on top of the water and can kill fish and birds, ruin beaches but nothing as yet has been invented to deal with this major problem. Dangerous metals such as mercury, arsenic and lead are also dumped into the sea. All of these examples have the ability to kill and damage the environment around it. Agricultural Environments : Unwanted plants or insects are nowadays killed with by herbicides and insecticides, in this case chemical rather than biological are used. Pesticides have the ability to damage the local environment, while herbicides may kill wild flowers as well as weeds and insecticides may kill Kris Charik R10D harmful pests but it can also kill butterflies and moths. Some of these chemicals are even dangerous to humans as well. 2) FIVE MAJOR POLLUTANTS: SULPHUR DIOXIDE   Ã‚  Ã‚  Ã‚  Ã‚  Sulphur Dioxide comes from both car and factory emissions.   Ã‚  Ã‚  Ã‚  Ã‚  Sulphur Dioxide is a poisonous gas which can kill plants and is the main gas that is involved in Acid Rain.

Wood this is a good Biofuel as it provides 13% of the world’s energy. As wood is used so much in the poorer countries and is insufficiently burnt resources are slowly decreasing in such countries as Africa and Asia. Nowadays there are special trees which can grow more quickly therefore it is possible in the right plants wood can produce substantial amounts of energy. Kris Charik R10D Alcohol can be made during fermentation and can be used in cars as fuel. It’s main advantage is that it is more enviromentaly friendly. It can also be used to make such things as perfumes, lacquer and explosives. 8)POLITICAL INVOLVEMENT : The Government wants more people to do more in the way of giving the poorer waste food and say that we should help them as much as we can. The government has also set up charities which raise money in order to give help to particulary the extremely poor countries by using T.V adverts to raise the money. Oxfam is possibly the most well known charity that helps poor countries, Oxfam however mainly helps such countries as India and Africa.

Chemistry Extended Essay Essay

To investigate the effect of 2-bromo-2-methyl propane concentration and temperature of the system on the rate of reaction of solvolysis of 2-bromo-2-methyl propane in 90% ethyl alcohol Done by: Habib Iscandar Hinn Friend’s Boy’s School June 22, 2007 To investigate the effect of 2-bromo-2-methyl propane concentration and temperature of the system on the rate of reaction of solvolysis of 2-bromo-2-methyl propane in 90% ethyl alcohol Introduction: The major product of the solvolysis of t -butyl chloride in 70 % water – 30 % acetone is t-butyl alcohol, with a small amount of isobutylene being formed as a by product And this is with accordance of first order kinetic and suggests a two step mechanism in which the rate determining step consists of the ionization of t-butyl chloride, and in this mechanism a carbonium ion is formed as inter- mediate and this bonds immediately to near by nucleophile (in this case nucleophile is a neutral molecule) the initial product is t-butyl carbonium ion. â€Å"Note1: if the nucleophile is neutral the product will be charged since the leaving group takes both bonding electrons away with it† So chemists have proposed to general types of mechanism: 1- Nucleophilic substitution Sn1 The ionization step in a Sn1 reaction is endothermic and much slower than the exothermic neutralization of carbonium ion by a nucleophile. And so the rate determining step being the unimolecular ionization of the t-butyl chloride equation 4, and as a result, the overall rate of reaction is not affected by changes in the concentration or kinds of nucleophilic reagents present. â€Å"Note2: the factor which determines the mechanisms employed is typically the nature of the substrate it self and not the particular nucleophile† â€Å"Note3: if the sum of the energy of the product is lower than the energy of the reactant the reaction is exothermic, and if the product have higher energy than the reactant the reaction is endothermic.† 2- Elimination E1 (elimination unimolecular) And because t-butyl chloride acts as a Lewis acid (an electrophile) and combines with a nucleophile to give a substitution product, so the major product of the solvolysis of t-butyl chloride in water-acetone solvent is t-butyl alcohol. (â€Å"Note4†: electrophile: an electron deficient atom, ion or molecule that as affinity for an electron pair, and will bond to a base or nucleophile.) (â€Å"Note5 â€Å": nucleophile: and atom, ion , or molecule that has an electron pair that may be donated in forming covalent bond to an electerophile.) Evaluating the mechanism: The only reactant that is undergoing change in the rate determining step is t-butyl chloride and so such reactions is a unimolecular and follow a first order equation (Sn1, E1). â€Å"This means that the rate of the reaction varies directly with the concentration of t- butyl chloride†. And since nucleophilic only participate in the fast second step, so their relative molar concentrations rather than their nucleiophilities are the primary product – determining factor, and by using nucleophilic solvent like water, so its high concentration will assure that alcohols are the major product, and because water have a high dielectric constant (e=81) so water molecule tend to orient them-selves in such a way as to decrease the electrostatic forces between ions. And an important factor is the salvations which refer to water molecules ability stabilize ions by encasing them in a sheath of weakly bonded solvent molecules: 1- Anions are solvated by hydrogen – bonding, 2- Cations are solvated by nucleophilic sites on water molecule (oxygen). And in this case of t-butyl carbonium ion the nucleophiles form strong covalent bond to carbon and converting the intermediate to a substitution product. The reaction mechanism is a sequential account of each transition state and intermediate in a total reaction, the over all rate of reaction is determined by the transition state of highest energy in the sequence, so the rate determining step is the rate determining step for both the Sn1 and E1 for t – butyl chloride. (â€Å"Note 6†: the water soluble organic solvent acetone is used to keep a reasonable concentration of t-butyl chloride in solution) The balance equation for t-butyl chloride solvolysis in water-acetone solvent is: The effect of concentration on the solvolysis of t-butyl chloride in 70 %water – 30 %acetone solvent. As the reaction proceeds the solution becomes increasingly acidic until all of the t -butyl chloride has reacted and all HCl that can form has formed. So we will monitor the reaction by allowing HCl formed to neutralize a predetermined amount of NaOH. An indicator dye (bromo-phenol blue) will change color when the NaOH has been neutralized, and clocking of the reaction should begin at the instant. So according to kinetic measurements: Rate of reaction = K [t – butyl chloride] Where K is the specific rate constant in S -1 and [t – butyl chloride] is the concentration of t-butyl chloride in M. Our kinetic measurement will depend on the determination of the amount of HCl produced by the reaction, so by monitoring the color change of the acid – base indicator, we will determine the time required for 10% of t-butyl chloride to hydrolyze by having 10 % as much NaOH present as T-butyl chloride. Rate = – d [Rcl] dt ; Where Rcl = -dt [Rcl] = K [Rcl] dt Rearranging, d [Rcl] = -K dt [Rcl] And integrating for t=0 to t=t will give; = Ln [Rcl] t – Ln [Rcl] 0 = – Kt – 2.303 Log [Rcl] 0 = – Kt [Rcl] t 2.303 Log [Rcl] 0 = Kt [Rcl] t Where [Rcl] 0: is the molar concentration at time t = 0 [Rcl] t: is the molar concentration at time t = t Two methods to calculate K 1- since the equation Kt = 2.303 Log [Rcl] 0 [Rcl] t Is an equation of a straight line (y=mx+b) with slope k. and intercept =0, a plot of 2.303 log [Rcl] 0 / [Rcl] t versus t should yield a straight line with slope k. 2- if the solvolysis reaction run to 10% completion Then, [Rcl] = 0.90 [Rcl] 0 Kt = 2.303 Log [Rcl] 0 = 2.303 log (1.11) 0.90 [Rcl] 0 And therefore, K = 0.104 T So by finding the value of K and compensate it in the rate of reaction equation â€Å"Rate = K[Rcl]† where the concentration of Rcl is known we can calculate the value of the rate of reaction and we will see it’s effect on the solvolysis of t – butyl chloride in 70% water – 30 % acetone solution. The effect of temperature on the solvolysis of t -butyl chloride in 70%water – 30%acetone solvent. In nearly every instance an increase in temperature causes an increase in the rate of reaction, â€Å"because the total fraction of all of the t – butyl chloride 1molecules having energies equal to or greater than activation energy (Ea) Corresponds to the shaded portion of the area under the curve increases by increasing the temperature† and by comparing the area for two different temperature, we see that the total fraction of t- butyl chloride molecules with sufficient kinetic energy to undergo reaction increases with increasing temperature and consequently, so does the reaction rate. â€Å"Note7: changing the concentration affects the rate of reaction changing the temperature affects the rate constant as well as the rate.† By finding the values of reaction rate constant K for different concentration of t-butyl chloride and different reaction temperature, we will find the effect of temperature on the solvolysis of t-butyl chloride in water acetone solvent. Quantitatively, K (s-1) is related to Ea and T by the equation K1 = Ae-Ea/RT1 †¦Ã¢â‚¬ ¦1 Ea is the activation energy, in joule / mole. (Jmol-1) A is a proportionality constant, in s-1 R is the gas constant = 8.314 Jmol-1K-1 e is the base of the natural logarithms. T is temperature in Kelvin. This relation ship is known as Arrhenius equation We measure Ea by taking the natural logarithm of eq.1 Ln K = ln A – Ea RT Thus, a plot of ln k versus 1/T gives a straight line whose slope is equal to -Ea/R and whose intercept with coordinate is ln A â€Å"Note8: Ea is the activation energy, a constant characteristic of the reaction† We can calculate the rate constant at some specific temperature if Ea and K at some other temperature are known. For any temp. T1 (known), Ea (known), K1 (known) K1 = A e -Ea/RT1 For any other T2 (known); (K2 unknown) K2 = A e -Ea/RT2 By dividing K1 over K2 K1 = A e -Ea/RT1 K2 A e -Ea/RT2 Taking natural logarithm of both sides, we get Ln K1 = Ea (1/T2 – 1/T1). K2 R Or in common logarithms (base 10 logarithms) gives: Log K1 = Ea (1/T2 – 1/T1) K2 2.303 R And by finding the value of K2 we will be able to find the rate of reaction at T2 and we will find the effect of temperature on the rate of solvolysis of t – butyl chloride in 70 % water – 30 % acetone solution. By finding the values of reaction rate constant K for different concentration of t-butyl chloride and different reaction temperature, we will find the effect of concentration and temperature on the solvolysis of t-butyl chloride in water acetone solvent. Procedure: Part A: the effect of concentration on the rate of solvolysis of t – butyl chloride in 70%water – 30%acetone solvent. a- Experimental procedure: to measure the time necessary for 10 % solvolysis of t – butyl chloride (0.1 M concentration) in 70 % water – 30% acetone solvent at room temperature.
