Clients sustainability chain assessment by novel grey approach: UAE construction companies

The clients sustainability chain (CSC) topic is found to be interesting. Weakness of the CSC only occurs when there are several bottlenecks across the CSC. CSC mapping compared against routine client’s operations has become essential. The construction industries (CIs) are huge in the United Arab Emirates (UAE) and dedicated to focusing on ordinary practices, except for key practices such as strategic costing quality and its corresponding metrics on a routine basis to build the CSC mapping module. Therefore, there is a necessity to develop an advanced CSC sustainability assessment module to map the future CSC of CIs in the UAE; this is respected as the first research gap (RG). Furthermore, to simulate the CSC mapping module, CIs are initiated to search the variant grey approach; this is respected as the second RG. To compensate for both RGs, the authors propose the grey performance importance index (GPII)-based variant approach with CSC mapping module to assess and map the CSC. An empirical research study is illustrated. The results reveal that the evaluated performance index (PI) is 65.80% and the CI is supposed to improve the performance up to 34.20% to target an ideal grey performance index. A constructed module is simulated by a grey set excluding a fuzzy set and can be changed for future challenging CSC practices–metrics; this is the novelty of the work.
