Book Synopsis Resource-Constrained Project Scheduling by : Christian Artigues
Download or read book Resource-Constrained Project Scheduling written by Christian Artigues and published by John Wiley & Sons. This book was released on 2013-03-01 with total page 235 pages. Available in PDF, EPUB and Kindle. Book excerpt: This title presents a large variety of models and algorithms dedicated to the resource-constrained project scheduling problem (RCPSP), which aims at scheduling at minimal duration a set of activities subject to precedence constraints and limited resource availabilities. In the first part, the standard variant of RCPSP is presented and analyzed as a combinatorial optimization problem. Constraint programming and integer linear programming formulations are given. Relaxations based on these formulations and also on related scheduling problems are presented. Exact methods and heuristics are surveyed. Computational experiments, aiming at providing an empirical insight on the difficulty of the problem, are provided. The second part of the book focuses on several other variants of the RCPSP and on their solution methods. Each variant takes account of real-life characteristics which are not considered in the standard version, such as possible interruptions of activities, production and consumption of resources, cost-based approaches and uncertainty considerations. The last part presents industrial case studies where the RCPSP plays a central part. Applications are presented in various domains such as assembly shop and rolling ingots production scheduling, project management in information technology companies and instruction scheduling for VLIW processor architectures.

This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite the many capabilities and contributions of available resource-driven scheduling techniques and models, they still suffer from a number of important limitations including their inability to (1) provide efficient resource utilization schedules that are capable of directly measuring and minimizing the negative impacts of resource fluctuations in construction projects; (2) analyze and optimize the impact of schedule acceleration strategies such as the utilization of multiple shifts on construction productivity, duration, and cost; and (3) analyze and quantify the impact of construction uncertainties on the generated project schedules in an efficient and effective manner especially for real-life large-scale construction projects. To overcome the aforementioned limitations, the main objectives of this study are to: (1) design innovative resource leveling metrics that can overcome the limitation of existing methods and develop a robust resource leveling model that is capable of maximizing resource utilization efficiency; (2) develop an advanced resource leveling and allocation model that is capable of simultaneously maximizing resource utilization efficiency and minimizing project duration while resolving all resource conflicts; (3) formulate a robust multiple shifts scheduling model that is capable of simultaneously minimizing project time and cost while minimizing the negative impacts of shift work on productivity, safety and cost; (4) develop a robust resource fluctuation cost model that is capable of minimizing resource fluctuation costs while minimizing project duration within the specified range of project duration; (5) develop an advanced project risk assessment model that is capable of providing fast and accurate estimates for the probability of project completion for large-scale construction projects; and (6) design a prototype multi-objective optimization system for resource driven scheduling in construction projects that integrates the research developments with commercially available project management software, Microsoft Project 2007, to facilitate their ultimate use and adoption by the construction industry. First, innovative resource leveling metrics are developed to circumvent the limitation of existing metrics and directly measure and minimize undesirable resource fluctuation. A robust resource leveling model is formulated by incorporating the newly developed resource leveling metrics to maximize resource utilization efficiency for construction projects. The optimization model is implemented using genetic algorithms in order to optimize resource utilization efficiency. Second, a resource leveling and allocation model is developed to simultaneously optimize resource leveling and allocation for construction projects. The model is developed as a multi-objective genetic algorithm to provide optimal tradeoffs between maximizing resource utilization efficiency and minimizing project duration while complying with all resource availability constraints. Third, a robust multiple shifts scheduling model is formulated to simultaneously minimize project time and cost while minimizing the negative impacts of shift work on construction productivity, safety, and cost. A multi-objective genetic algorithm is utilized to implement the model in order to support construction planners in generating optimal tradeoffs among project time, cost, and labor utilization in evening and night shifts. The model is also designed to consider labor availability constraints in order to optimally distribute the limited availability of labor on the competing shifts. Fourth, a robust resource fluctuation cost model is developed to provide the most cost effective and efficient resource utilization for construction projects. The model is developed as a novel multi-objective optimization model that is capable of modeling and minimizing overall resource fluctuation costs (i.e. idle costs, release and rehiring costs, and mobilization costs) and analyzing and optimizing the potential tradeoffs between minimizing resource fluctuation costs and minimizing project duration. Fifth, a robust project risk assessment model is developed to overcome the limitations of existing probabilistic scheduling methods including (a) the inaccuracy limitation of the PERT method due to its 0́−merge event bias0́+ by incorporating an accurate multivariate normal integral method; and (b) the impractical computational time of the Monte Carlo simulation method by incorporating a newly developed approximation method. The model is named FARE (Fast and Accurate Risk Evaluation). The development of the FARE model facilitates the optimization of resource-driven scheduling while considering the impact of relevant risks and uncertainties. Sixth, a prototype multi-objective optimization for resource driven scheduling system is developed to seamlessly integrate the aforementioned research developments with commercially available project management software, Microsoft Project 2007, to facilitate their ultimate use and adoption by the construction industry. The system is designed to (1) retrieve project scheduling data from MS Project that can be utilized it in the developed optimization models, and store the generated optimization results in a binary file that can be accessed and processed by MS Project; (2) enable construction planners to benefit from and utilize the practical project scheduling and control features in MS Project during their analysis of the optimal schedules generated by the developed models in this study; and (3) facilitate the input of project parameters and the visualization of the obtained solutions using the newly developed graphical user interface modules. The main research developments of this study contribute to the advancement of current practice in resource scheduling and planning in construction projects and can lead to: (1) an increase in the resource utilization efficiency in construction projects which can produce significant improvements in construction productivity, cost and duration; (2) an improvement in utilizing the limited availability of resources; (3) a reduction in the duration and cost of multiple shifts operation while circumventing the negative impacts of shift work on productivity, safety, and cost; and (4) an enhancement in analyzing construction project risks in order to improve the reliability of project performance.

This book was released on 2015 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: In construction industry, contractors usually manage and execute multiple projects simultaneously within their portfolio. This involves sharing of limited resources such as funds, equipment, manpower, and others among different projects, which increases the complexity of the scheduling process. The allocation of scarce resources then becomes a major objective of the problem and several compromises should be made to solve the problem to the desired level of optimality. In such cases, contractors are generally concerned with optimizing a number of different objectives, often conflicting among each other. Thus, the main objective of this research is to develop a multi-objective scheduling optimization model for multiple construction projects considering both financial and resource aspects under a single platform. The model aims to help contractors in devising schedules that obtain optimal/near optimal tradeoffs between different projects’ objectives, namely: duration of multiple projects, total cost, financing cost, maximum required credit, profit, and resource fluctuations. Moreover, the model offers the flexibility in selecting the desired set of objectives to be optimized together. Three management models are built in order to achieve the main objective which involves the development of: (1) a scheduling model that establishes optimal/near optimal schedules for construction projects; (2) a resource model to calculate the resource fluctuations and maximum daily resource demand; and (3) a cash flow model to calculate projects’ financial parameters. The three management models are linked with the designed optimization model, which consequently performs operations of the elitist non-dominated sorting genetic algorithm (NSGA-II) technique, in three main phases: (1) population initialization; (2) fitness evaluation; and (3) generation evolution. The optimization model is implemented and tested using different case studies of different project sizes obtained from literature. Finally, an automated tool using C# language is built with a friendly graphical user interface to facilitate solving multi-objective scheduling optimization problems for contractors and practitioners.
Book Synopsis A Practical Approach to Project Scheduling by : Ramkumar Harikrishnakumar
Download or read book A Practical Approach to Project Scheduling written by Ramkumar Harikrishnakumar and published by . This book was released on 2017 with total page 73 pages. Available in PDF, EPUB and Kindle. Book excerpt: A well-managed project results in efficient scheduling of the interrelated components of work tasks, resources, stakeholders and budgets plans. The goal is for project managers to be able to generate an initial schedule at an early stage of product development. Due to complex product development, uncertainties and variabilities exists during manufacturing process. Variable processing times may lead to multiple critical paths within the system. Based on the real world demands of project managers two objectives are considered: Identification of multiple critical paths within the system and minimize completion time of the activity by optimal resource allocation. To solve this problem, a mixed integer linear programming model (MILP) is proposed. The Multiple critical path scheduling approach (MCPSA) is developed to identify multiple critical paths dominant in a system. A criticality index is used as performance metric to measure the intensity of the critical path in comparison to the project completion time. An interface of MS- Project with a simulation software (@RISK) is used to obtain the results. An application of two auger screws used in extrusion molding machines from a leading manufacturer in Kansas is used to illustrate the case study models and the MCPSA algorithm.

Book Synopsis Interdisciplinary Planning by : Kan Chen
Download or read book Interdisciplinary Planning written by Kan Chen and published by Routledge. This book was released on 2017-09-04 with total page 237 pages. Available in PDF, EPUB and Kindle. Book excerpt: Critiques of traditional urban planning are numerous. The debate about direction within the profession and why urban planning seems to be in a state of despair continues. However, and as Milan J. Dluhy and Kan Chen note, the more critical issue is the future direction of planning, particularly interdisciplinary planning. In this regard, they note five principal areas of concern: planning is action research, planning is knowledge driven, planning is both process and technologically oriented, planning is interdisciplinary, and planning is adaptive to emerging concerns.Reviewing the literature and empirical studies on roles and attitudes, the editors note that planners seem committed to symbols and expressions of advocacy as well as traditional planning doctrine. This emphasizes rational planning and neutral policy roles for practitioners. Without a guiding theory to give a unified approach to practice, planners remain free to select the role most compatible with their personal background and training. This volume asserts that diversity need not be a drawback as long as careful analysis and open planning processes are used.This title will be an invaluable resource. Part I illustrates the critical dilemmas in planning, Part II focuses on planning skills and orientations, the third part focuses sharply on planning roles, while the final section answers a fundamental question: can interdisciplinary planning offer a more useful perspective than others on how to achieve more successful planning outcomes?
