Abstract:

Efficient project management in the construction industry depends on optimizing project scheduling and material ordering, two interdependent processes that significantly impact both costs and durations. Traditional approaches often address these processes separately, neglecting the trade-offs between scheduling costs and material procurement costs. Furthermore, existing studies frequently overlook real-world constraints, such as limited storage space at construction sites. To bridge these gaps, this paper investigates the project scheduling and material ordering problem with limited storage sp

Abstract:

Construction contractors often rely on external funding to manage financial deficits caused by irregular cash inflows and outflows. To address these cash flow challenges, contractors typically adjust the start times of project activities to prevent shortages while minimizing the overall project duration. However, in severe cases, operations may need to halt if cash flow issues cannot be adequately resolved. This study introduces an alternative strategy to prevent cash shortages by allowing for the temporary suspension of activities, known as activity splitting. In this approach, operations are

A successful project is subjected to timing and cash flow management. Different objectives are considered in project scheduling, and financial goals are the most challenging ones. Lack of liquidity is one of the problems that cause a delay. To avoid these delays, project financing is essential. In most projects, a credit line (CL) is considered a source of cash. The contractors should remain below the credit limit imposed by the lender bank. This limit may cause an extension in duration because some activities cost too much, and the available cash cannot satisfy the expenses. In this paper, a

Abstract:

Dynamic programming has been utilized to optimize scheduling of repetitive projects. The optimization criterion of existing techniques, however, is limited to minimizing the project duration and does not account for the impact of such optimization on the project cost. While the minimization of the project duration may reduce the project indirect costs, it does not guarantee a minimum total cost for the project. In practice, minimizing the overall cost of a project is frequently regarded to be more important than minimizing its duration. The objective of this paper is to present a flexible mode

Abstract:

Lateness is a common risk factors in construction projects that may result in additional costs and fines according to the project agreement. In order to meet the predetermined specifications and completion schedule, the contractor must carefully plan the project and sequence the work tasks to create a rational schedule. This study focuses on the use of probabilistic scheduling to overcome delayed construction projects, especially in the case of the Pogalan Health Center development project. The process involves data collection, network planning, identification of critical paths, implementation

Abstract:

Several techniques were developed to improve resource allocation in construction projects, yet few in repetitive construction projects. Accordingly, this research aims at minimizing resource consumption and fluctuations using Line-of-Balance (LOB) repetitive scheduling technique. An optimization model has been developed consisting of three modules: LOB schedule module, resource leveling module, and optimization module. The model helps determine the optimum (a) start time for each activity considering any needed delays to level resources, (b) number of crews travelling from one unit to another,

Abstract:

Many construction projects contain several identical or similar units, such as floors in multistory buildings, houses in housing developments, sections of pipelines or highways. Repetitive processes arise from the subdivision of a generalized construction process into specific activities associated with particular units. In many cases it is possible to perform individual processes (repeated in each units) in alternative ways (modes). Regardless of the construction project procurement system, duration and cost are the key factors determining project’s economic efficiency and fulfillment of the

Abstract:

ABSTRACT The current development of construction projects lead to construction projects being more complex and complicated. The success or failure of a project can be due to inadequate planning and less effective controls, resulting in inefficient projects. This will result in delays, lower quality, and increased implementation costs. All of those problems are expected to be overcome with Presedence diagram method by reducing the impact of delay and swelling of project cost by crashing with applied overtime. Acceleration of duration on the critical path jobs was performed. The results wi

Abstract:

We introduce a multimode resource-constrained project scheduling problem with finish-to-start precedence relations among project activities, considering renewable and nonrenewable resource costs. We assume that renewable resources are rented and are not available in all periods of time of the project. In other words, there is a mandated ready date as well as a due date for each renewable resource type so that no resource is used before its ready date. However, the resources are permitted to be used after their due dates by paying penalty costs. The objective is to minimize the total costs of b

Abstract:

New shipbuilding projects are required to work quickly according to schedule. For this reason, it is necessary to have a planning and scheduling for shipbuilding so that it is received by the shipowner on time. It is inevitable that in every implementation practice there are various possibilities that can cause delays, such as delays in implementation, design changes, weather effects, delays in material supply, construction failures, and planning errors. This study aims to analyze the scheduling of ship x project and analyze the causes of delays in QCS block project at the PT. Karimun Sembawan

Abstract:

The increasing number of construction projects together with the limited resources of organizations led to tough competition for achieving project goals. Time, cost, and quality have been known as the project iron triangle. Project managers attempt to allocate the appropriate resources and make the best decisions for accomplishing projects with the shortest durations, lowest costs, and the highest quality. No study has examined the time–cost–quality trade-off problem with decision-making approaches. In this study, the fuzzy multi-criteria decision-making (MCDM) methods are exploited to choose
