Construction Schedule

Delivery of the prefabricated components may be disrupted by low productivity and various of traffic restrictions, thus delaying the prefabricated construction project. However, planning of the prefabricated component supply chain (PCSC) under disruptions has seldom been studied. This paper studies the construction schedule-dependent resilience for the PCSC plan by considering transportation costs and proposes a multi-objective optimization model. First, the PCSC planning problem regarding schedule-dependent resilience and resultant transportation cost is analyzed. Second, a quantification scheme of the schedule-dependent resilience of the PCSC plan is proposed. Third, formulation of the resilience-cost tradeoff optimization model for the PCSC planning is developed. Fourth, the multi-objective particle swarm optimization (MOPSO)-based method for solving the resilience-cost tradeoff model is presented. Finally, a case study is presented to demonstrate and justify the developed method. This study contributes to the knowledge and methodologies for PCSC management by addressing resilience at the planning stage.

Inventory Replenishment

Vendor Managed Inventory (VMI) is an approach in managing inventory between supplier and consumer in an supply chain system. In VMI concept, supplier keeps its inventory at consumer’s warehouse, meanwhile inventory ownership belong to supplier until it is used by consumer. The advantage of VMI is to reduce inventory replenishment ordering process and to reduce the usage of consumer’s warehouse space. Some key factors to achieve VMI success are: coordination, communication, production system and inventory order reliability.When supplier is a subsidiary of consumer, coordination between the two usually puts them not at an equivalent level, especially when supplier’s infrastructure is not as good as that at consumer. This research is a case study at a pharmaceutical company and its supplier which acts as its subsidiary. Information and data gathered by deep interview to all parties responsible for supply chain, production, and inventory at supplier and consumer sides. The results show advantages and obstacles in applying VMI, thus long-term commitment is needed to reach a better performance.
