The purpose of this research is to demonstrate, using statistical modelling, that for company economic performance, besides economic resources, human capital and its well-being, psychological comfort and motivation measured through psychological constructs are also important. For the research, two companies from the industry, two batches of employees, homogeneous, comparable in terms of the subjects’ socio-demographic characteristics and economic indicators evolution were analysed. The results indicate as good predictors, statistically significant, for the personal satisfaction of employees from the two industrial firms, with a direct and measurable effect on the economic performance of the company: time management and burnout for both companies and, for company F1, also salary satisfaction. The statistically significant differences between the two companies for the yield per employee for turnover and net profit are explained from the perspective of psychological constructs. Thus, the importance of psychological constructs in measuring and diagnosing employees to ensure an upward evolution of company economic indicators and yield per employee is demonstrated.","PeriodicalId":51029,"journal":{"name":"Economic Computation and Economic Cybernetics Studies and Research","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2024-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140382327","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A resource renting problem is a project scheduling problem in which the required resources should be rented, and the goal is to find a schedule and resource renting plan such that the total cost of the resources minimises. Traditionally, the model of a resource renting problem contains single-mode activities and a single objective function. This research aims to present a new mathematical model for a bi-objective multi-mode resource renting problem. The objectives are to minimise the project makespan and also the total cost of resources, including the time-independent resource procurement costs and time-dependent resource renting costs, simultaneously. A novel evolutionary algorithm, namely the Multi-Objective Water Cycle Algorithm (MOWCA), is employed to solve this NP-hard problem. In order to evaluate the proposed algorithm, the Non-Dominated Sorting Genetic Algorithm (NSGA-II) is applied, too. A set of instances is selected from the digital library of project scheduling problems to analyse the performances of evolutionary algorithms. The results of the experimentation are quite satisfactory.","PeriodicalId":51029,"journal":{"name":"Economic Computation and Economic Cybernetics Studies and Research","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2024-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140382956","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigates the correlations between stock market indices in representative countries or regions along the Belt and Road using a generalised complex network based on the maximum information coefficient. Also, the dynamic correlation characteristics of the focused stock market indices are analysed utilising the minimum spanning tree. Firstly, the results show that, since the introduction of the Belt and Road policy, the Chinese stock market has emerged as the center of the stock index networks, establishing stronger associations with the stock indices of other countries or regions. Secondly, throughout all sub-sample periods, especially before the policy was put forward, the stock index networks of the stock market indices of representative countries or regions along the Belt and Road generally exhibit aggregation patterns of regional geography in the mass. Thirdly, the correlation between these stock market indices is significantly strengthened during extreme shocks. Finally, since 2015, with the progressive deepening of investment and trade between China and other countries or regions along the Belt and Road, the degree of relationship between these stock market indices under discussion has been undergoing changes.","PeriodicalId":51029,"journal":{"name":"Economic Computation and Economic Cybernetics Studies and Research","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2024-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140382000","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
