The warehouse is usually built information about warehouse buildings and teach correct according to the shape of land. Choosing a rectangular or a facts with the help of the warehouse simulation software. This square building is a preference. software is free. Also, the software does not need extra workforce, statistics and logistics knowledge and On the exterior shape of the warehouse; we will design and programming language. Thus, the software compares write a program that compares a few simple forms of warehouses easily. warehouses with scientifically utilizing the Information Systems and present it to the use of the logistics sector. This Over the last 15 years, many logistics warehouses have been warehouse will be tested by comparing some exterior shapes built. The majority of these warehouses are rectangular and of warehouses. According to the results obtained from the the doors are on the short side of the rectangle. By looking at program, which warehouse will appear to be more each other, the construction of the depot continued in this way. advantageous for use. The logistics industry can use this These warehouses are not good warehouses in terms of program for their existing depots or new ones to build. It will performance, have been proven by simulation program that be possible to simulate real life in a virtual world, before we developed. At least from now on, this program will be building the depots helpful to make a higher performance warehouses. Thanks to DepotsComparison simulation program measures this program you have the possibility to further develop your performance during storage use. The result of comparison is existing depot by simulating it without breaking walls down. reduction in staff, equipment, warehouse investment costs. It The WarehouseComparison simulation program has been also increases the warehouse performance. developed to be used in the external warehouse selection of the depot. DepotsComparison simulation program is; simple, specialized on a specific topic, just as much logistical and Warehouse Comparison software can be requested free of statistical information as needed, user friendly, free, charge from [email protected] attainable, not requiring consultancy and training. Key Words: Warehouse Building External Shape, Simulation Program, Warehouse Doors and Performance Relation, 1.1 NEED OF STUDY Rectangular and Square Warehouse comparison, Warehouse Shape and Performance Relations, Warehouse Layout, Depots horizontal movements are carried out by people, Warehouse improvement. stackers and conveyors. There is a relationship between the horizontal shape of the warehouse and horizontal 1. INTRODUCTION movements. This relationship is also the main factor in the selection of the ideal warehouse. When many warehouses are examined in the logistics sector, the interesting thing is; it is observed that hundreds of When two warehouses of the same square meter are taken depots are rectangular with a large number of depots with into consideration, which warehouse is more efficient? gates on the short edge. (Google Earth, 2016). The comparison of the shortest movements in the path and • Is rectangular depot shaped, ideal for usage in all time between the palette addresses of the rectangular and form of depots? square stores and the doors will be measured. • Is there a better way to use any warehouse? 1.2 LITERATURE REWIEW • How can we improve our existing depot? According to Ed Acker “The economics of modern commercial Before the construction phase, a simulation program is warehouses dictate that goods are processed in minimal required to determine which warehouse is the best turnaround time.” (Acker, 2011) warehouse design should be warehouse for the purpose of use. There are many functional and efficient; in order to increase workers simulation programs available. But these programs are not productivity and to reduce the operating costs. © 2018, IRJET | Impact Factor value: 6.171 | ISO 9001:2008 Certified Journal | Page 981 International Research Journal of Engineering and Technology (IRJET) e-ISSN: 2395-0056 Volume: 05 Issue: 02 | Feb-2018 www.irjet.net p-ISSN: 2395-0072 According to Rob O'Byrne “Time is money and distance is time.”, (O'Byrne,2015). It is aimed to make the shortest distance calculation in warehouse simulation program. The Travel Distance Calculation is available in the LM Labor Management module in the SAP ERP system which measures employees in the warehouse. Worker performance is measured with this distance. There are two different ways of measuring distance (SAP). Two methods are used to measure distance: • Euclidean (direct distance) method • Manhattan Meter method (Actual movement distance) Euclidean method; As Figure 1 shows, it measures the shortest distance between two points. Figure-3 A warehouse in Tuzla Istanbul Google 2016 and 2003 benchmark There were many simulation programs before the Figure-1 Euclid warehouses became widespread. Table 1 lists the simulation program examples. The distance method according to Manhattan Meters is the measurement of the actual movement distance according to Table-1: Simulation Programs in 1997 the layout of the shelves, as shown in Figure 2 Program Training Consul Producer 2017 Price Internet Address Name Cost tancy Systems https://www.are Arena(Sim Modelling Yes Yes 3000$ Yes nasimulation.com an) Corp. / http://www.appli edmaterials.com/ global- AutoSimulatio AutoMod Yes Yes Yes Yes services/automati ns Inc. on- software/automo d https://www.awe AweSim!
