SLS creates the route and delivers according to merchandise type, quantity and available vehicles. Route modifications may occur if deliveries become cancelled or adding new deliveries. The routing office attempt to maintain tight scheduling by: Providing customers with accurate and convenient time windows. Minimizing operational cost. Giving drivers consistent routes. In addition to merchandise delivery, Sears Product Service (SPS) operates 12,500 service vehicles in addition to the technicians providing these services. Theses technicians provide the various installation, home improvement, and appliance repair services. The SPS manages over 15 million calls annually with the sixth largest fleet in the US. Both services utilize the regional model and attempts to succeed in the following: Maximize the completion of service Minimize cost Enhance customer service Solution ESRI developed new systems for both SLS and SPS to improve services, consolidate operations, and reduce cost. ESRI focused attention to Sears existing main-frame based delivery order systems and product services system. ESRI created a new system able to deal with the complex issues associated with home-delivery and home service by providing data communications with the existing system. The new EHDS and CARS system utilizes GIS technology which differ from the previous system. The EHDS and CARS system builds routes and downloads customer data and locate customer location. Using distance and customer information, the route improvement models finalize the route for delivery. The result of the enhanced model, resulted in Sears operating within larger street networks and providing faster delivery times. The new system allows Sears the opportunity to reduce drive time by 6% increasing their ability to adjust to cancelled orders and reduce overtime by 15%. This project has also led ESRI to create more software designed to handle these situations. Submit your homework as one single attachment.
