Designing warehouse infrastructure requires a systematic approach to the problem and including a set of variable business, technology, and organizational factors. Systemic approach requires parallel consideration of all relevant design factors while monitoring the impact of the decisions made on the quality of the solution and the way and conditions of functioning of external systems and processes related to the design object.
The system approach to design can be backed up by applying computer techniques at different stages of the project and at different scales. Computer support involves both the acquisition and processing data necessary in the design process, decision support, and documentation.
 
Computer aided design of logistic infrastructure
Methods supporting the design of logistics infrastructure include:
-      Procedures and algorithms for solving specific decision problems.
-      Tools for acquisition and processing data, especially databases on past material flows.
-      Warehouse process (mapping) tools.
-      Calculation tools to assist solving common design cases.
-      Mathematical modeling and optimization tools for selected design issues.
-      Simulators with different application range.
-      Tools for visualization of work results, including 3D visualization.
Practically all of these tools require computer support, but especially the last three groups provide significant support for project work by allowing multi-faceted and multidimensional testing of solutions.
Due to the complexity of warehouse processes and the variety of factors affecting their shape, decision support systems are required both at the design stage and for the management of the facility. For this purpose, warehouse management systems (WMS) are used as a design data source on the one hand, and platforms for implementing new design and organizational solutions on the other.
 
SIMMAG 3D as a toll for computer-aided design of warehouse infrastructure
SIMMAG 3D is a system for computer-aided design of warehouse infrastructure focused on visualization as a major facilitation in design work.
SIMMAG 3D is a result of cooperation between the Faculty of Transport, WUT and Logifact Systems Sp. z o.o. It is a tool for direct support of design work during the development of new warehouse systems and as a tool for managing existing systems working within the warehouse management system.
SIMMAG 3D is a modular system of computerized support of warehouse infrastructure design. It contains the following functionalities:
-      Developing a three-dimensional warehouse models based on the physical and functional structure of the working warehouse (possible use of WMS data).
-      Visualization of stock levels and selected parameters and characteristics of processes.
-      Developing own libraries of storage structures – exchangeable between users.
-      Simulation of selected warehouse processes with particular focus on customer orders and shipping processes, which are one of the most laborious, costly, and sensitive warehouse processes.
-      Dimensioning and organization of warehouse processes from the point of view of efficiency and cost of implementation.
-      Geographical and functional localization of warehouse facilities in logistics network from the point of view of spatial distribution of customers, suppliers and conditions of the supply chain.
-      Operation in online environment, using cloud-based solutions.
