Almazkoor, F B (2014) Two-stage methodology for managing and controlling material flow between multiple construction projects. PhD thesis, Clemson University, USA.
Abstract
There is a strong connection between managing and controlling material flow in a supply chain and its performance. While this is true in all supply chains, it is particularly true in the construction supply chain (CSC) where the total demand for parts is finite, the storage space available can be small, and the variability in consumption is high. On the other hand, effectively controlling the CSC can have a significant impact on controlling risk and buffering their impact so that projects stay on schedule and within budget. Currently, a common control of the CSC is with a push-based material ordering system based on the initial construction schedule and, then, holding a tremendous amount of inventory. Project managers even speak of the desirability to "flood the site" which means having as many of the construction materials on-site as early in the project as possible. It is not uncommon for a year-long construction project to have tens of acres dedicated to storage and for this area to be completely full early before the project begins. Further, each project is controlled completely independently from all other project even if they are for the same customer or being built by the same firm. A new methodology for controlling the CSC that represents a paradigm shift from the current system is proposed in this dissertation. This two-stage methodology applies to products that can be used among a few construction projects being executed simultaneously. Stage 1 mirrors the current push procurement strategy but Stage 2 allows transshipments between sites. Further, the two stages collaborate in the sense that information is shared and decisions updated based on current, global knowledge. The methodology uses deterministic optimization models with objectives that minimizing the total cost of the CSC. To illustrate how this methodology can be used in practice and the types of information that can be gleaned, it is tested on a number of cases based on the real example of multiple construction projects in Kuwait.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
