Abstract
This paper provides a systematic approach for the analysis and design of construction supply chain operation models. Based on the Supply Chain Operations Reference Model of the Supply Chain Council, this research studies sup- ply and demand behavior, using a bridge superstructure construction process as a case study. This paper uses the SCOR Model and applies Dynamic Simulation software, namely, “SIMPROCESS”, to assist in establishing a hierarchical model to explore the behavior of the construction supply chain process and develop a performance evaluation method that can help improve the supply chain management (SCM) of the construction project. Santrauka Šiame darbe sistemingai analizuojami ir kuriami statybų tiekimo grandinės procesų modeliai. Remiantis etaloniniu tiekimo grandinės procesų modeliu, kurį sudarė Tiekimo grandinės taryba, nagrinėjama pasiūlos ir paklausos elgsena, at-vejui tirti pasirinkus tilto perdangų statybos procesą. Naudojant SCOR modelį ir dinaminio modeliavimo programinę įrangą “SIMPROCESS”, darbe sudaromas hierarchinis modelis, leidžiantis nagrinėti procesų pobūdį statybų tiekimo grandinėse, ir sukuriamas veiklos efektyvumo vertinimo metodas, kuris gali padėti pagerinti statybų projekto tiekimo grandinės valdymą (TGV).
Highlights
There have been many recent improvements in construction technology, and a number of new construction technologies have been introduced in construction projects
Vrijhoef and Koskela (1999) noted that the development of supply chain management (SCM) in the construction industry is behind other industries due to a lack of systematic construction project supply chain design
The study implemented SCOR structure together with dynamic simulation technology to bulld a construction project supply chain model, and developed a construction project supply chain performance evaluation method to improve the performance of the construction project SCM
Summary
There have been many recent improvements in construction technology, and a number of new construction technologies have been introduced in construction projects. The paper aimed to present a supply chain design and behavior analysis method to build a construction project supply chain model on the basis of SCOR, and study a series of demand-and-supply processes ranging from material purchasing, stocking and pro-. Entity – Entity represents order flow from the precast yard to three kinds of material suppliers (steel bar, concrete, and prestressed tendon), and the flow of the manufacturing process. Plan: the process to plan the balance of supply and demand, especially timely delivery to the precast yard was very important for concrete usage, the project department had to plan the quantity of concrete to order according to the construction schedule and total inventory. If the result is smaller than d, conduct simulation, OptQuest and target value comparisons repetitively until all searched solutions are the same
