In engineering design, optimization methods are frequently used to improve the initial design of a product. However, the selection of an appropriate method is challenging since many methods exist, especially for the case of simulation-based optimization. This paper proposes a systematic procedure to support this selection process. Building upon quality function deployment, end-user and design use case requirements can be systematically taken into account via a decision matrix. The design and construction of the decision matrix are explained in detail. The proposed procedure is validated by two engineering optimization problems arising within the design of box-type boom cranes. For each problem, the problem statement and the respectively applied optimization methods are explained in detail. The results obtained by optimization validate the use of optimization approaches within the design process. The application of the decision matrix shows the successful incorporation of customer requirements to the algorithm selection.

Since high performance is essential to the functioning of emergency departments (EDs), they must constantly pursue sensible and empirically testable improvements. In light of recent advances in computer science, an increasing number of simulation-based approaches for studying and implementing ED performance optimizations have become available in the literature. This paper aims to offer a survey of these works, presenting progress made on the topic while indicating possible pitfalls and difficulties in EDs. With that in mind, this review considers research studies reporting simulation-based optimization experiments published between 2007 and 2019, covering 38 studies. This paper provides bibliographic background on issues covered, generates statistics on methods and tools applied, and indicates major trends in the field of simulation-based optimization. This review contributes to the state of the art on ED modeling by offering an updated picture of the present state of the field, as well as promising research gaps. In general, this review argues that future studies should focus on increasing the efficiency of multi-objective optimization problems by decreasing their cost in time and labor.

In the present paper we introduce an approach to implementing parallel metaheuristic optimization frameworks which is used in the design of the framework HeO. This experimental cross-platform framework is a collection of popular optimization methods implemented in C++ as algorithmic skeletons. The key feature of the discussed approach is the wide usage of metaprogramming and design patterns which allow to increase the reusability of the code and ease the process of hybrid algorithms construction for the end-user. We consider framework structure and implementation details and provide the results of numerical experiments for some well-known optimization problems.

Purpose The importance of international markets has increased in the past years and will further increase in the future. This offers potential for being competitive, but especially for small- and medium-sized enterprises (SMEs) is going along with a variety of risks, e.g. the competition in the domestic market intensifies. Nevertheless, in most cases, SMEs with foreign operations are more successful than SME operating solely in the domestic markets. Nevertheless, the internationalization activities of SME are often unsystematic and emotional, especially when looking for distribution partners. The research project “Empirical based development of an instrument for identifying and making decisions about the choice of market entry and the selection of distribution partners of SME of the tool and cutlery industry when developing foreign markets” deals with this topic. In this paper the results of a literature review and an expert discussion regarding market development and especially the process of finding distribution partners for foreign markets are presented. Also, further steps in the project dealing with aspects of realizing the detected success factors by using quality management methods are explained. Design/methodology/approach The first step comprises a literature review and an expert discussion with leading managers of SME, with the aim to receive information about market entry decisions and selection of distribution partners. Therefore, a literature review and an expert discussion with leading managers of SME are carried out. The discussions are evaluated with MAXQDA©, a software for qualitative data analysis. Next, a questionnaire is designed for a quantitative analysis of the topic and will be evaluated by using SMART-PLS. Then, the results will be used as input variable for a quality function deployment for identifying appropriate measures for implementing the prior identified success factors. Thereby, also quality management methods and techniques will be used for finding the “right” measures. In this context, also a method for selecting distribution partners will be developed which is based on the logic of supplier evaluation. Finally, an Excel-based tool will be developed which includes the results of the project and allows companies easily applying them. Findings A literature review and an expert discussion within the tool and cutlery industry have been carried out and analysed. Thereby, the need for action regarding the selection of distribution partners has been revealed as essential step for success in foreign markets. Literature mostly deals with aspects like choosing appropriate countries for market entry and market entry strategy but not with distribution partners. Expert discussion also has shown that choosing distribution partners is often managed with gut feel. It lacks a criteria-based approach for optimizing this step during the internalization process. Originality/value Finding adequate distribution partners for a successful entry into foreign markets has not been investigated thoroughly yet. The project offers insights into determining factors for the selection process and improves the distribution partner selection by using quality management methods, for instance, by adapting the fundamental procedure of supplier assessment for distribution partner assessment.

Pahandut Seberang Village has an average middle to the lower level of economy in the community, so most of the people still need assistance from the government. In Pahandut Seberang Village, the selection of recipients of the Smbako program assistance is still the old way by using from paper. The assessment process is still not transparent in nature and the selection process is very slow and receipt of Sembako programs assistance are not being on target. Therefore, to overcome this problem, a Decision Support System (SPK) is created to help the Pahandut Seberang Village in selecting the recipients prospective of Sembako program assistance In designing and building the system are using 2 development methods, namely the Waterfall method as a software development method and the Simple Additive Weighting (SAW) method as a decision support system method in its calculations. Where the saw method has 4 stages, namely determining the criteria, determining the suitability, making a decision matrix based on the criteria and normalizing the. The final result is obtained from the ranking, namely the sum of the normalized matrix multiplication R with the weight vector so that the largest value sas a solution. This system testing uses a Black-box testing system. The test results show that the system created has been running according to the expectations of the researcher. This research produces a decision support system for selection of the recipients prospective that can provide recommendations for the recipients prospective the Pahandut Seberang village.

Abstract A method of implementing three-precision point synthesis into the merit function of kinematic optimization problems was developed. The addition of synthesis reduced the order of the merit function from eight to four. The new merit function was tested on three optimization methods and compared to the standard non-synthesis optimization merit function. It was discovered that the performance of the new synthesis merit function depended heavily upon which of the three precision points were selected for use in the synthesis calculations. Subsequently, a method of pre-optimization selection of synthesis points was developed. It was found that when a favorable selection method was employed, the synthesis based merit function performed well, optimizing to a comparable merit function value in about 50 percent fewer function evaluations.

The authors describe a software suite for determining tilt degrees of tower-type structures according to ground laser scanning indication. Defining the tilt of the pipe is carried out with a set of measured data through approximating the sections by circumferences. They are constructed using one of the simplest search engine optimization methods (evolutionary algorithm). Automatic filtering the scan of the current section from distorting data is performed by the method of assessing the quality of models constructed with that of least squares. The software was designed using Visual Basic for Applications. It contains several blocks (subprograms), with each of them performing a specific task. The developed complex enables obtaining operational data on the current state of the object with minimal user participation in the calculation process. The software suite is the result of practical implementing theoretical developments on the possibilities of using search methods at solving optimization problems in geodetic practice.

The optimization methods and, in particular, metaheuristics must be constantly improved to reduce execution times, improve the results, and thus be able to address broader instances. In particular, addressing combinatorial optimization problems is critical in the areas of operational research and engineering. In this work, a perturbation operator is proposed which uses the k-nearest neighbors technique, and this is studied with the aim of improving the diversification and intensification properties of metaheuristic algorithms in their binary version. Random operators are designed to study the contribution of the perturbation operator. To verify the proposal, large instances of the well-known set covering problem are studied. Box plots, convergence charts, and the Wilcoxon statistical test are used to determine the operator contribution. Furthermore, a comparison is made using metaheuristic techniques that use general binarization mechanisms such as transfer functions or db-scan as binarization methods. The results obtained indicate that the KNN perturbation operator improves significantly the results.
