In project scheduling, it is feasible to reduce the duration of a project by allocating additional resources to its activities. However, crashing the project schedule will impose additional costs. Numerous research has focused on optimizing the trade-off between time and cost to achieve a set of non-dominated solutions. However, the majority of the research on time-cost trade-off problem develo...

The problem faced by one of the private construction companies in Jakarta, Indonesia is delay completing grounding and lightning protection installation project. This resulted both material immaterial losses for company. Factors that are thought to cause delays this project include man, machine, material, environment factors. method used research Critical Path Method (CPM) Crashing accelerate d...

This paper develops a single wholesaler and multi retailers mixture inventory distribution model for a single item involving controllable lead-time with backorder and lost sales. The retailers purchase their items from the wholesaler in lots at some intervals throughout the year to meet the customers’ demand. Not to loose the demands, the retailers offer a price discount to the customers on the...

Many project tasks and manufacturing processes consist of interdependent timerelated activities that can be represented as networks. Deciding which of these subprocesses should receive extra resources to speed up the whole network (i. e., where activity crashing should be applied) usually involves the pursuit of multiple objectives amid a lack of a priori preference information. A common decisi...

This paper investigates the ordering decisions and coordinationmechanism for a distributed shortlife-cycle supply chain. The objective is to maximize the whole supply chain’s expected profit and meanwhile make the supply chain participants achieve a Pareto improvement. We treat lead time as a controllable variable, thus the demand forecast is dependent on lead time: the shorter lead time, the b...

one of the important problems in project management is lack of available resources in proper time at project site that leads to lack of project implementation in due date. this problem may be lead to time delay in sending resources from suppliers and related origins in supply chain to project site. therfore, to better resources managmenet and also the improvement of supply chain condition, the ...

Abstract This research conducted in one construction company Indonesia, the was facing several problems, many projects that already ended have delays. Overdue payment of can reach Rp 252.544.148.-. For calculating late save researcher using Critical Path Method (CPM)-Crashing. CPM-Crashing method accelerate project duration by increase resource budget, so doesn’t need to pay overdue payment. Th...

In carrying out the PPLP Banten Building construction project, it experienced delays. The causes of delays are addition time, changes in shop drawings and material Then solution theMicrosoft project is an alternative crashing method 4 hours overtime work shifts. research results obtained 18 jobs that on critical path 43 jobs. normal total duration 942 days fee Rp. 569.100.000 using AHSP. 678 da...
