This paper considers the problem of predicting a supply chain cost for prefabricated building construction under an uncertain situation. Based on the Activity-Based Costing (ABC) method, we establish a computational model to estimate the total cost of the prefabricated supply chain. The model can assist in not only finding the critical areas for cost reduction of the whole supply chain but also analyzing other costs of prefabricated construction projects. Furthermore, we provide a numerical example of prefabricated building construction to validate the results.

Construction Accidents

Construction industry is recognized and best described as an accident-prone industry, being characterized with a plethora of occupational risks. Review of literature on construction accidents revealed that a copious number of theories have been propounded over the years by different theorists, though some of these theories were criticized. In addition to this were the multifarious models developed by different proponents at different times. However, accidents are an unplanned event that are common on the building construction sites, involving materials, objects and people with attendant damages, loses and injuries. Moreover, existing models were developed to investigate the causations of accident with the aim of preventing its occurrence. Effort to analyze the existing models, with criticism in view, was the aim of this research, which was accomplished by pointing out the limitations of applicability of the models and ascertaining the need for an improved model. A major gap was discovered, in that most of these models concentrated on accident causations and investigations with little or no emphasis on preventive measures via the duties of the construction stakeholders (client, consultant, contractor, health and safety agency) at the preconstruction and during construction stages. Having considered the strengths and weaknesses of the existing models, it was discovered that another, but improved, model was needed and such model will consequently enable construction stakeholders in putting up and implementing accident preventive measures on the building construction sites, as all stakeholders have significant roles to play in preventing accident.

The analysis of the overall risk level of the system and the reduction of risk control costs are the key links to avoid the safety risks of prefabricated construction. In this paper, a dual-objective optimization model is constructed with the objective of minimizing system security risk loss and control cost to minimize the level of construction safety risks for prefabricated building while minimizing cost consumption. This paper introduces risk correlation into the optimization model based on the 2-additive fuzzy measure and solves it with discrete multiobjective particle swarm optimization (discrete-MOPSO). The example shows that considering the correlation of risks in different situations can better reflect the interaction relationship between the risk factors of building construction safety and improve the rationality of the optimization model.
