“…The time needed for solving these problems grows exponentially with the increase of the problem's size [9,31] -this is why mathematical and heuristic methods do not enable finding solutions to complicated construction problems within an acceptable period of time [11]. In the view of many authors, metaheuristic algorithms seem to be the most appropriate measures for scheduling and task sequencing [21,30,31].…”

“…To create a schedule, one has to determine the order of tasks and their start times -this has to be performed in such a way that specific objectives of the project are achieved whilst at the same time, fulfilling organisational conditions and conforming to planning constraints [11,17,26,43]. Some of the construction project planning objectives include: minimising the duration of the project; minimising or providing evenness of the resources consumption; maximising the construction project economic value for the contractor [11,43]. Organisational conditions may include, for example, availability of construction activities performance modes, or the need to ensure the continuity of work performed by various groups of workers.…”

In this article, the author analyses the state of the research of the multi-mode, resource-constrained, projectscheduling problem (MRCPSP). Both general and construction-industry-specific applications were studied and compared-in particular, algorithms and methodologies used for solving the different variations of this scheduling problem. Based on the analysis, the author suggests future research ideas.

“…-Step 3: Calculate the project duration (T) and total shareable equipment utilization cost (EUC) for the revised project schedule using Equations (8) and (9). The present model is designed to calculate the total shareable equipment utilization cost (EUC) based on the number of shifts (y) that shareable-type (k) equipment had utilized on each day (t).…”

Construction equipment is often shared among many construction projects. In a real construction project, supply of this critical equipment is often limited, which often generates negative impacts on project performance. Multiple shifts are very effective and efficient for achieving schedule acceleration while resolving resource conflicts among project activities for shareable equipment. This paper presents a novel multiple-equipment shift-scheduling model that is capable of optimizing the utilization of critical and shareable construction equipment in multiple shifts for construction projects. The model is designed to help construction planners identify and generate optimal shift work plans and schedules that can simultaneously minimize the project duration and total shareable equipment utilization cost while complying with all of the availability constraints. An example is analyzed to illustrate the use of the present model and demonstrate its new and unique capabilities in optimizing equipment utilization in multiple shifts for construction projects.

“…Jaśkowski and Sobotka researched the duration optimization with evolutionary algorithms under deterministic conditions. In the optimized process, authors considered the actual condition (the renewable resources, the different technological and organizational variants) which could affect the results [7]. Ma et al studied the impact of the uncertainty for the schedule plan.…”

The schedule plan is the important basis of construction project. Because of the uncertain of the construction project environment, the existing schedule plan is very hard to meet the demand of the actual progress, and it is schedule plan optimization decision that is an important progress in the schedule management. The schedule plan optimization decision is a decision-making progress, in which the collaboration among the multi objectives, the constraint conditions, and the collaboration among the multi stakeholders should be considered. In this paper, the dominance-based rough set will be used to make decisions based on characteristics of the schedule plan optimization decision. Through the case study, the decision made by the dominance-based rough set can be understood easily, and improve the Scientific nature in the uncertain construction environment.
