2.0 Introduction
The study on warehouse management system (WMS) was done since early 20th century and there are lots of topics that related to this study. Nowadays the WMS become more advance so that they need to improve their performance to be better. In order to achieve that, there are lots of studies that can be review and its can been categories as follows:
2.1 Reverse Logistics
In logistics process there are two types of the process which reverse logistics process network and forward logistics process network. But when it’s related to warehouse operation there will be more focus on reverse logistics process network. Reverse logistics process network can be defined as the process of planning, implementing and also controlling the efficient, effective inbound and storage of the second goods. This definition is studied by Fleischmann (2001). Figure 1 shows the illustrate concept of forward and reverse logistics within the supply system. In reverse logistics usually involving of retrieve, transport and dispose of a good.

Salema et. al. (2007), studied the design of a reverse distribution network and they found that the most of the proposed models on the subject are case based and for that’s why they lack generality. The redesign model of a generic reverse logistics network has capacity limits, multi-product management and uncertainty on product demands and the returns are considered. Then a mixed integer formulation is developed. In this f...

... been coded in VB.net (Visual Basic 7.0). It was debugged using Microsoft tools that had allowed them to validate the code by following the algorithm flow. Jayant et. al. (2011) also used simulation model, however they are using different software which ARENA 11.0 with simulation package. The studies area is to analyze the future performance of the network and to understand the complex relationship between the parties.
Shi et. al. (2011), an adaptive routing strategy (ARS) had been introduced for transportation networks. This route is made adaptively for the system based on real-time information. The study is related to the shortest problem in networks with random arc cost. Their objective is focus on the problem of finding a shortest path in the transportation network with random arc. They used dynamic stochastic shortest path (DSSP) model to solve their problem.
Once they develop and implement this inventory control system, inventory records are going to be upheld truthfully and that they will get the accurate standing of the inventory up-to-date. In order to maintain the steady continuous supply for production need... ... middle of paper ... ... ory holding costs, ordering costs, and shortage costs, and have a classification system for inventory items. In conclusion, while reading the case study, I saw much disorganization throughout the company’s entire system.
reaches its capacity management every winter when the volume of demand for products increases dramatically. During this time, sales are faster than the system who automatically calculates sales average every five weeks and orders inventory. Then, the manager of the store has to input manually order to keep up with fast rate of sales during winter time. Walmart 32nd St. relies on its information technology systems to take bests decisions reduce risk, increase efficiency of existing resources and forecast accurately on current sales in order to balance capacity management. Data is the key for capacity management efficiency. Technology plays an important role for system perspective at Walmart 32nd St. where the manager focuses on how the structure behavior of the system determine certain events. Walmart 32nd St. use smart devices that help the manager or supervisors to overview data, and get store records in seconds from certain products or activities. Before managers used to waste time and spend hours and days getting data, doing calculations, and then reaching to conclusions. Now days, the data is very accurate and available on
The most important stage of the value chain is inbound logistics, because they have the chance to build value in advance. Thus, the factors of this phase are considered to be upward action. In this case, logistics task including the goods received from suppliers cargo storage, loading and unloading and the inside of the transport of goods, and lay the product on the shelf. Tesco is trying to retain consumer choice, at the levels of the store, at the same time increase the efficiency of its distribution system. For damaged goods and products quality control program of the application, it provides less unfairly assume cost, company a great opportunity, therefore, to prevent these costs on to consumers by to potentially add value for the company.
The one reason of Walmart’s success is its Supply Chain and Logistics management. The company is saving significant cost by using its information system properly that managed inventory level, orders, sales and other information. Any information can be easily accessible at each store at any
Ava Beane has considered, within the case study, two possible alternatives that would help enforce the four objectives given from the Scientific Glass executives. These four objectives are: improve order fulfillment time for both old and new customers, reduce customer backorders; reduce sales team involvement in tracking and expediting delayed product orders; and increase inventory turnover which would reduce overage and underage costs. Beane hypothesize that to achieve these objectives, the company would either have to centralize all warehouse functions or to completely outsource the warehouse process (Schmidt and Wheelhouse, pg. 6-7).
Reverse Logistics is the process of planning, implementing, and controlling the efficient, cost effective flow of raw materials, in-process inventory, finished goods and related information from the point of consumption to the point of origin for the purpose of recapturing value or proper disposal. It is the process of returning goods from consumers back to suppliers. Also comprises of sending new or used products backup stream for repair, remanufacturing, reusing, recycling and refurbishing activities.
In the competitive environment, it is necessary for moving products involves reception of products at an intermediate location, store, repackage, clear customs and transport to final destination. The other factor in the supply chain logistics is speed given information flows fast in the internet era. The customer expects everything quick accustomed to the instant status access to the information. With the real time inventory, customer expects the location of the product, it is next scheduled movement and the final delivery schedule.
Reverse logistics has become an increasing concern for many companies over the last decade. It is the process of the movement of goods, moving in the opposite direction, such as from the customer to the business. Some important processes involved are the physical movement of goods, customer support, warehousing and repair. Reverse logistics handles the issue of handling resources effectively. Rogers and Tibben-Lembke (1999) defines reverse logistics as the ‘process of planning, implementing, and controlling the efficient, cost effective flow of raw materials, in-process inventory, finished goods and related information from the point of consumption to the point of origin for the purpose of recapturing value or proper disposal’. This definition is seen to...
Christopher (2011) argues that the term called reverse logistics is used to depict the step of taking products back, generally at the end-of-life, but also for repair and recall. Reverse logistics can be defined as a chain of process to recover or sell the value of a product. That is if a company think supply chain stream in reverse, the one can make a decision the best way to deal with the bounced product. Especially, reverse logistics has received keen attention in the supply chain literature, since it mirrors the capacity of a company within supply chain to affirmatively effect the relationship that customers (Horvath et al., 2005). In addition, reverse logistics triggers main cost result for both the enterprise and its supply chain (Daugherty et al., 2005). As mentioned above, reverse logistics has been an essential structural component to make strategy in whole supply chain (Daugherty et al., 2001). Among a variety of industrial fields, automotive industry is the sector that has one of the complicated supply chains as car enterprises have vertical business relation with their suppliers to control thousands of parts for making a car. It means that the car parts companies should have their own supply chain to maintain relationship with their collaborating companies, and logistics also have to be operated to meet service demands of customers in supply chain. This dissertation presents a study of the effect according to reverse logistics strengthen in automotive parts supply chain.
It is undeniable that Inventory Management is an important key to success at Walmart. This paper will discuss the two main methods of Inventory Management used by Wal-Mart: Material Requirements Planning and Just-in Time. Next we write about the technical means of keeping track of inventories, like RFID tags. We conclude by discussing how Wal-Mart, one of the world’s largest retailers, manages its inventories. Material Requirements Planning (MRP) Walmart needs to make sure that consumers are satisfied all the time, not only with the quality of service being provided to them, but with the quality of the product they are planning.
There are four approaches that an organization can choose from to analyze logistics systems. These are namely: materials management versus physical distributions, cost centers, nodes and links, and logistics channels.
ATM Network can be modeled by an connected graph G(V,E).The performance of the multicast routing in a system can be measured by following criteria.

Inventory management involves planning, coordinating, and controlling the acquisition, storage, handling, movement, distribution, and possible sale of raw materials, component parts and subassemblies, supplies and tools, replacement parts, and other assets that are needed to meet customer wants and needs (Collier & Evans, 2009). In order for business and supply chains to run smoothly, they must meet all the listed requirements for effective inventory management. Thus, inventory management must be managed wisely in order to be a successful an...
Logistics is the designing and managing of a system in order to control the flow of material throughout a corporation. This is a very important part of an international company because of geographical barriers. Logistics of an international company includes movement of raw materials, coordinating flows into and out of different countries, choices of transportation, cost of the transportation, packaging the product for shipment, storing the product, and managing the entire process. The concept of logistics is fairly new in the business world. The theoretical development was not used until 1966. Since then, many business practices have evolved and logistics currently costs between 10 and 25 percent of the total cost of an international purchase.
