Joint Decision

In order to solve the joint optimization of production scheduling and maintenance planning problem in the flexible job-shop, a multiobjective joint optimization model considering the maximum completion time and maintenance costs per unit time is established based on the concept of flexible job-shop and preventive maintenance. A weighted sum method is adopted to eliminate the index dimension. In addition, a double-coded genetic algorithm is designed according to the problem characteristics. The best result under the circumstances of joint decision-making is obtained through multiple simulation experiments, which proves the validity of the algorithm. We can prove the superiority of joint optimization model by comparing the result of joint decision-making project with the result of independent decision-making project under fixed preventive maintenance period. This study will enrich and expand the theoretical framework and analytical methods of this problem; it provides a scientific decision analysis method for enterprise to make production plan and maintenance plan.

Proper maintenance planning is required to ensure the upkeep for buildings. However, maintenance of university buildings are often plague with challenges such as poor  maintenance, increasing maintenance backlogs and insufficiency of budget allocation. Thus, maintenance prioritisation is practiced as part of the solution to these challenges. The purpose of this paper is to provide an overview of issues and factors related to maintenance prioritisation through literature review. It discusses the issues faced by maintenance manager in deciding priorities for maintenance work. The consideration for factors when deciding maintenance priorities is also presented in this paper. While there are a lot factors listed in previous literatures, this paper attempts to provide a general guideline for the factors that are considered in setting maintenance priorities. These factors are organisation's objective, risk, performance measurement, resources, and stakeholders. By following and incorporating these factors in deciding priorities, a maintenance programme can be designed to achieve better maintenance planning in universities.
