In this paper, the problem of determining the best schedule for a set of projects has been modeled in the form of a generalized tardiness flowshop (GTF) problem. We develop a set of heuristic algorithms for minimizing the total tardiness of jobs in a GTF problem. In the generalized version of tardiness flowshop problems, a job is considered to be a collection of operations and there is a due da...

Project scheduling is the part of project management that deals with determining when intime to start (and finish) which activities and with the allocation of scarce resources to theproject activities. In practice, virtually all project managers are confronted with resourcescarceness. In such cases, the Resource-Constrained Project Scheduling Problem (RCPSP)arises. This optimization problem has...

Many studies on the resource-constrained project-scheduling problem have been published, but literature further considering multi-mode or multi-project issues often occurring in the real world is rather scarce. In this research, two heuristic algorithms are developed to solve a multi-mode resource-constrained multi-project scheduling problem (MMRCMPSP). The first, a parallel scheduling algorith...

The planning phase of every construction project is entangled with multiple and occasionally conflicting criteria which need to be optimized simultaneously. Multi-criterion decision-making (MCDM) approaches can aid decision-makers in selecting the most appropriate solution among numerous potential Pareto optimal solutions. An evidential reasoning (ER) approach was applied for the first time in ...

As complexity and size of projects increase so do the problems associated with the scheduling and management of the design, manufacturing and assembly processes. In the context of large projects the ability to optimise the scheduling and allocation of these processes can also aid in tendering for contract as well as the management of the project itself. Many large projects will be constructed a...

During the construction phase, participants in a multi-contract project acquire external real-time scheduling information from other involved parties and use this to make appropriate decisions in regard to project control. There are two major obstacles to project participants gaining efficient access to external information in a distributed data environment: (1) the variety of data structures t...

CRIBA is a project that aims at industrializing thermal renovation processes of buildings. It consists in designing and configuring make-to-order insulated panels that will be installed on the external facade of the buildings to meet the thermal renovation objectives. Our study provides an optimization model that comprehensively plans supply chain network, which delivers insulated panels to the...
