Construction projects are one of the most complex types of projects due to unpredictability process, operation and resource constraints. This leads to crucial role of project manager for the success of construction projects. Therefore, construction manager’s project selection is a significant issue. On the other hand, systematic selection of the project manager is necessary. In the past, systematic selection has not been considered and further personal and expert’s opinions have been toward project manager selection. In order fill this void, a research was conducted to select the construction project manager based on the competence model. Initially, by comparing standards of project management competence, project management standard of Australia was selected as the most appropriate model. Then, by distributing a questionnaire to experts of the decision-making team using the SWARA method, the criteria and the sub criteria were weighted. Weighting results showed that sub-criteria of leadership ability, ability to conduct and ability to manage environmental change were identified as the most important sub-criteria. Then, using the WASPAS method, project management alternatives were ranked.

In today's competitive world, production and inventory control in small and medium enterprises (SME) is considered as an important issue by managers, because of the influence of factors such as fluctuations in demand and failure of machines. Network Failure Prone Manufacture Systems (NFPMs) are type of production systems that failure of machines is assumed for them. In this paper, a multi-product network failure manufacturing system with perishable items is studied. The production control policy is based on the hedging point policy that contains producing and maintaining of products in order to respond to demand and avoid shortages. In this system, demand is constant and shortages (backlog and lost sale) have been allowed. The main goal of this paper is to determine the optimal production rates that minimize expected value of total production, holding, shortage, and perishable costs. Because of uncertainly and complexity of these systems, simulation optimization has been done using ARENA software. Finally, numerical example will show the efficiency of the proposed approach.
