TY - CONF TI - Increasing On-Time Delivery by Selecting the Appropriate Job-Sequencing Order C1 - Haifa, Israel C3 - 18th Annual Conference of the International Group for Lean Construction SP - 457 EP - 466 PY - 2010 AU - Chin, Chang-Sun AD - Ph.D., A.M.ASCE, Kevinchin255@yahoo.com ED - Walsh, Kenneth ED - Alves, Thais AB - In case a promised delivery date is not provided by a product or service provider, customers usually request their expected delivery dates when they place an order. However, there is always the possibility of a difference between the time a customer wants to receive a product/service and the actual time the customer receives a product/service. In a construction project, the Request-For-Information (RFI) is a formal question or clarification that the contractor asks the architect/engineering (A/E) firms regarding details in the plans, drawings or specifications. The A/E firms usually do not provide ―Promised Due Dates‖ for each RFI. Instead, the contractor puts the expected response time on each RFI. As a result, discrepancies between when the contractors want the questions answered and the time they are received almost always occur and are sometimes large. One of reasons for this large gap can be found in the job-sequencing problem. The hypothesis of the research is that if the performance of a production system is related to job sequencing order, then selecting an appropriate sequencing order will improve the performance and increase the on-time delivery. The research discusses the different types of sequencing rules and conducts a simulation study to test the hypothesis. The result shows that on-time delivery can be increased by selecting the appropriate job sequencing order.
