1.4 Thesis objectives

manner the investigation of the significant parts of SCM in development, particularly after Vrijhoef and Koskela (2000) presented four jobs of SCM in development that spurred numerous researchers in contemplating the area.

Figure 0.2, so as to realize efficiency in construction logistics, the four analyzes are commonly conducted: transportation analysis, material purchasing and storage analysis, site layout analysis, and material handling analysis (Polat et al., 2007; Liu and Tao, 2015). Transportation accounts for a high proportion of the logistics cost in several industries, often between one-third and two-thirds. In the construction industry, transportation costs may be considerably greater because of high-volume and low-value raw materials. Therefore, it causes an increase in requests for transportation capacity, but it does not essentially come with proportional income. It is suggested to employ an efficient method for controlling transportation means and creating a load consolidation of shipped goods to decrease the transportation cost. Material purchasing and storage take under consideration the look for efficient solutions within the determination of buying material quantity for every planned period and therefore the storage of the purchasing materials to avoid the risks of shortage due to the supply delay or changes in demand. Site format arranging is led to appear for the easiest course of action of transitory offices on the destinations to constrict the transportation distances of on location work force and gear. Material dealing with ought to be successfully arranged and executed to stay away from the negative impacts of material deficiency or a lot of material stock nearby. It is identified with numerous exercises like passing on, lifting, situating, shipping, bundling, and putting away of materials.

1.2 Research questions

RQ1: What are the present focuses and future trends of decision-making in construction logistics and SCM during the major construction phases?

RQ2: How to model and optimize the integrated CSC network regarding the TPL partner as the focal coordinator for the SC operations?
