The warehouse layout problem includes assigning several different product types to confident areas of warehouse so that the cost of material handling from docks of the warehouse can be minimized. The layout of a warehouse may need to be modified to accommodate new product lines or to add more flexibility to the warehouse operations. In order to guarantee the success of a project, a detailed planning process should be followed. Concerning above, Decision Support Systems (DSS) are developed to assist companys personnel (e.g., engineers and decision makers) to modify the arrangement of warehouse layout. Lately, DSS have been affected by new information technologies in design, deployment and implementation. Developing Web-Enabled decision support systems is a comprehensive area under discussion that describes how to build data-driven Web-enabled decision support systems using web programming framework. Availability and easiness of interactions in such a DSS frame inspired us to focus on developing an online warehouse location problem to simply deciding about productions which are always traffic. So that user specifies the area of the warehouse in number of bays, places for docks around the warehouse, gives the frequency of their usage, along providing demands and required area for each product type. Then the problem will be solved quickly to find the proper location of each product type for minimum material handling cost and information would be deposited. We follow these processes through an example in web pages.
