Abstract
10 years pass from enforcement of a large-scale retail store law, and store modification is planned with many large-scale shopping centers. In such a modification plan, parking lot improvement is also carried out at the same time in many cases. In this approach, we applied the simulation technology to the parking lot inside layout change that a commercial operator planned. Moreover we evaluated how a service for users was improved by estimating smoothly loading and unloading the automobiles as the time required. In addition, we surveyed before and after the parking lot inside layout change, and we arranged a precision of the estimated value by the simulation and the problem at the time of the application. Improvement target of the service level in the parking lot becomes clear by adopting such a technique for a planning stage, and it is assumed that layout that raised convenience more is provided.
