In this paper, a time-dependent and bi-objective vehicle routing problem with time windows (TD-BO-VRPTW) is proposed, which is a new extension of classical vehicle routing problem. Time-dependency is presented for the situation that vehicle’s travel speed is affected by its departure time and the distance between two customers. The total transportation costs and time costs are two objectives optimized simultaneously through constructing a bi-objective mixed integer linear programming model. To deal with this problem, the non-dominated sorting genetic algorithm II (NSGA-II) is adopted to obtain the Pareto optimal solution set. In the numerical examples, the RC108 from Solomon's benchmark set is employed and the results in the Pareto front show the efficiency of NSGA-II for the TD-BO-VRPTW. To further test the performance of this algorithm, two objectives are optimized separately and then the sum of two objectives is also optimized. Through comparing these results with solutions in the Pareto front, it can be concluded that the algorithm is reliable, and the results in Pareto front are competitive because there is a trade-off between two objectives.","PeriodicalId":48763,"journal":{"name":"Advances in Production Engineering & Management","volume":"180 1","pages":""},"PeriodicalIF":3.6,"publicationDate":"2019-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77327128","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The performance of wire EDM is mainly based on the electrical conductivity of both electrode wires and workpiece materials. The aim of research is to increase cutting speed (CS) of high strength low alloy (HSLA) hardened steel by determining main contributing input process parameters and effect of cold treatment on electrical conductivity of brass wire at –70 °C. Fractional factorial design is used to determine the relationship of CS with input process parameters includes; open voltage, pulse on time, pulse off time, wire tension, flushing pressure of deionized water and brass wires (cold treated – CT, and non-cold treated – NCT). Empirical model for CS is developed based on selected input process parameters and their contribution is analyzed through ANOVA technique. It is learned that pulse on time, pulse off time and wire electrode are the main contributing input process parameters that provide assistance to increase CS of wire EDM. In wire electrodes, cold treated brass wire is observed as a best alternative to enhance machining performance with an increase of electrical conductivity by 24.5 %. © 2019 CPE, University of Maribor.

Evaluating MSS’ robustness is integral to production and service provisioning, and thus the influence mechanism should be clearly revealed for assisting professionals in the company in improving the robust performance. In this paper, we present an effective methodology for explicating the impact of cooperation uncertainty on the robustness of MSS from a complex system standpoint. This methodology characterizes MSS as a topological network consisting of serval service subsystems, and constructs the measure metrics system of which the validity and applicability are proved theoretically from the dimension of structure and performance. Furthermore, it simulates the cooperation interruption from four different scenarios with algorithms, and finally takes an elevator manufacturing service network as the case to illustrate this novel methodology. The simulation findings suggest that identifying the critical paths in MSS and standardizing the cooperation mechanism within and among core manufacturing service principals outperform the other measures in improving the robustness of MSS.","PeriodicalId":48763,"journal":{"name":"Advances in Production Engineering & Management","volume":"8 1","pages":""},"PeriodicalIF":3.6,"publicationDate":"2019-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87787042","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Contemporary challenges in ID projects have led to their growth in their complexity, which in recent years has driven researches in recent years to publish numerous papers that deal with this topic, demonstrating its importance in current project management research. Nevertheless, existing literature lacks in generally accepted framework that considers specifics of project complexity in ID projects. Thus, new framework was developed, based on a two-round Delphi survey, building upon existing TOE (technology-organisation-environment) framework with new empirical insights given from the experts in the field of ID projects. The main contribution of the paper is the validation of existing TOE complexity factors, in the context of International Development projects. Additionally, eight new complexity factors were proposed by the experts, and it was concluded that Environmental complexity had the biggest impact on International Development projects. From a managerial perspective, proposed complexity framework can be used for making a complexity footprint, which could indicate the critical areas of the project where complexity could be expected. In addition, the model represents a novel theoretical lens for assessing complexity in ID projects. 2019 CPE, University of Maribor.

In today's environment, where necessity for survival in the market is to deliver the goods in time, it is crucial to optimize production plans. Inspired by real sector manufacturing system, this paper demonstrates the discrete event simulation (DES) supported by the genetic algorithm (GA) optimization tool. The main aim is to develop the simulation framework as a support for the daily planning of manufacturing with emphasis on determining the size and entry order of the product batches within specific requirements. Procedures are developed within the genetic algorithm, which are implemented in Tecnomatix Plant Simulation software package. A genetic algorithm was used to optimize mean flow time (MFT) and total setup time (TST) performance measures. Primary constraint for on-time delivery was imposed on the model. The research results show that solutions are industrially applicable and provide accurate information on the batch size of the defined products, as well as a detailed schedule and timing of entry into the observed system. Display of the solution, in a simple and concise manner, serves as a tool for manufacturing operations planning. © 2019 CPE, University of Maribor.

However, more empirical research is still needed that adopts a contingent approach and studies the differentiated role each of these two functions plays in PMFI. Based on Information Processing Theory, the two flows of information that PMFI requires, from marketing to purchasing and vice versa, are used as a PMFI proxy. The study posits a positive impact of these two information flows on a typical NPD performance indicator, namely, its speed, and a positive moderation of environmental dynamism on that effect. Data from 141 Spanish firms are used to conduct a moderated multiple regression analysis to test these effects, showing that the marketing information impact of NPD speed is positive regardless of the level of environmental dynamism. However, the effect of purchasing information on NPD speed is positive when the rate of environmental dynamism is medium or high, but negative when it is low. These results will help managers to assess when each one of these flows should be promoted. Above all, they stress the need to control for possible asymmetries in the role the different functions play in functional integration. © 2019 CPE, University of Maribor.

Objective function is used to minimise travel distance while using the lowest number of vehicles. According to the maximum-minimum distance clustering method, a three-stage algorithm is proposed. First, the maximum-minimum distance method is employed to cluster customer points into the lowest number of groups. Second, according to the maximum vehicle capacity, the load demand in each group is adjusted to create suitable customer points in each clustering group by adopting 'push-out' and 'pull-in' operations. Third, a tabu search is used and an optimised route for each group is generated to minimise the total travel distance. Numerical experiments, some on the benchmark data set, are presented to verify the feasibility and effectiveness of the proposed algorithm. The computational results show that the performance of the proposed algorithm is better in terms of both optimised travel distance and less computation time when the problem size is less than 75. The results also show that when the customer points are in a cluster distribution around the depot, the algorithm achieves better performance.","PeriodicalId":48763,"journal":{"name":"Advances in Production Engineering & Management","volume":"21 1","pages":""},"PeriodicalIF":3.6,"publicationDate":"2019-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79325337","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Typically, in a multiple U‐ line facility, each U‐line is designed to work independently which may cause some workstations were not fully functioned. The PAUL aimed at increasing the utilisation of the whole facility by allowing cross‐trained workers to work on the opposite legs of the adjacent U‐lines (multi‐line workstations). This configuration is easier to implement than parallel U‐lines due to no restriction in terms of the lengths of U‐lines to be paralleled and hidden expenditures that could be incurred in shop floor reconstruction. Since the line balancing of the PAUL is NP‐hard and many conflicting objectives need to be optimised simultaneously, the evolutionary meta‐heuristic which was the hybridisation of the multi‐objective evolutionary algorithm based on decomposition (MOEA/D) and particle swarm optimisation (PSO), namely MOEA/D‐PSO, was developed to effectively solve the problem. In addition, the decoding algo‐ rithm to convert the solutions obtained from MOEA/D‐PSO into the PAUL’s configuration was proposed. The performance of MOEA/D‐PSO was evaluated against MOEA/D and multi‐objective particle swarm optimisation (MOPSO). The experimental results reveal that MOEA/D‐PSO outperformed its rival algorithms under the convergence‐related performance. © 2019 CPE, University of Maribor.
