Enterprise Resource Planning Software or ERP doesn't live up to its acronym. Forget about planning- it doesn't do much of that- and forget about resource, a throwaway term. But remember the enterprise part. This is ERP's true ambition. It attempts to integrate all departments and functions across a company onto a single computer system that can serve all those different departments' particular needs. That is a tall order, building a single software program that serves the needs of people in finance as well as answering the needs of the people in human resources and in the warehouse. Each of those departments typically has its own computer system optimized for the particular ways in which the department does its work. But ERP combines them all together into a single, integrated software program that runs off a single database so that the various departments can more easily share information and communicate with one another.

This study was carried out objectively to study features of simulation software used by automobile manufacturers in North India. This study provides a list of more than 207 evaluation criteria. These criteria were derived mainly from practical experience of automobile industry users, from simulation software developers and some of them were identified during analysis of the literature. A criterion was marked down to make comparative evaluation of these simulation software. The study verifies empirically the state of simulation tools used currently in Indian Automobile Industry in comparison to the developed framework on the basis of various statistical/ data mining methods. An open source software "Smart Sim Selector" was developed that helps users in customized selection of simulation software based on their specific requirements.Finally some guidelines have been suggested in the form of 6-Steps for simulation software selection process.
