We consider criticality in project networks having imprecise activity duration times. It is well known that finding all possibly critical paths of an imprecise project network is an NP-hard problem. Here, based on a method for finding critical paths of crisp networks by using only the forward recursion of critical path method, for the first time an algorithm is proposed which can find all pos...

A project network often has some activities or groups of activities which can be performed at diierent stages of the project. Then, the problem of nding an optimal time or/and optimal order of such an activity or a group of activities arises. Such problems emerge, in particular, in house-building management when the beginnings of some activities may vary in time or/and order. We consider a math...

Emotional intelligence is considered to be important for project managers affect performance, but emotional does not always play an effective role. Based on conservation of resource theory, this article explores the impact managers’ performance. The results show that affects performance through mediating effect commitment, and complexity negatively moderates commitment. This provides practical ...

A project network often has some activities or groups of activities which can be performed at different stages of the project. Then, the problem of finding an optimal/acceptable time or/and optimal/acceptable order of such an activity or a group of activities arises. Such a problem emerges, in particular, in house-building management when the beginnings of some activities may vary in time or/an...

agricultural mechanization project must be identified in a short time frame to do a certain way; otherwise, cost is not the time to come and will also result in reduced yield. to avoid these costs in farming systems is necessary in any region that agricultural mechanization projects are and scheduling and planning as well as scientific until activities included in the project to fruition are do...

The online observation of a construction site and processes bears significant advantage to all business sector. BIM is the combination of a 3D model of the project and a project-planning program which improves the project planning model by up to 6D (Adding Time, Cost and Material Information dimensions to the model). RFID technology is an appropriate information synchronization tool between the...
