Cheng, M Y; Huang, K Y and Hutomo, M (2018) Multiobjective dynamic-guiding PSO for optimizing work shift schedules. Journal of Construction Engineering and Management, 144(9): 04018089, ISSN 0733-9364
Abstract
Work shift system is commonly used in construction projects to meet project deadlines. However, evening and night shifts raise the risk of adverse events and thus must be used to the minimum extent feasible. The three objectives of the work shift problem are to minimize project duration, project cost, and total evening and night shift work hours while effectively handling relevant scheduling constraints. This study proposes a new multiobjective approach that hybridizes dynamic guiding, chaotic search, and particle swarm optimization (PSO) functions, named multiobjective dynamic guiding chaotic search particle swarm optimization (MO-DCPSO). The approach can overcome the drawbacks of PSO in solving discrete domain problems and recruit more nondominated solutions kept in the archive. A real case was employed to verify the robustness and efficiency of the proposed approach. The result also indicated that MO-DCPSO is more fitting for solving practical project control issues.

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
