The samples were subjected to the research of the influence of used fillers, binders and additives on their properties. Testing was carried out in a certified laboratory and included checking the dimensions of the test bodies, weighing on the calibrated weight, determining the volumetric weight, determining the maximum load of the testing samples using special devices and then determining the compressive strength, or flexural tensile strength according to the relevant formulas. The final part of the testing also examined the morphology and mapping of the chemical composition with a focus on carbon, oxygen and aluminum using an electron microscope. The obtained results clearly show an increase in tensile and compressive strength using dispersed carbon fibre reinforcement of approximately 4 MPa. The conclusion of the article provides an overall summary of the results obtained and a summary of the features.","PeriodicalId":48763,"journal":{"name":"Advances in Production Engineering & Management","volume":"140 1","pages":""},"PeriodicalIF":3.6,"publicationDate":"2020-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86630652","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 production of customized goods poses new challenges for all areas of functioning of production systems. It is necessary to adopt such rules and methods that will allow a flexible response to product design changes and their demand In the organization of production flow (materials and information). The article presents research carried out in the SmartFactory laboratory of the Poznań University of Technology regarding the impact of the structure of products (customization) on the realization of current production orders. The research was carried out using the FlexSim simulation environment. Based on simulation experiments for three forms of organization of production flow with varying degrees of flexibility of production resources, an analysis was made of the time of execution of various sets of production orders and the level of use of available working time. The results of research indicate that in the production of products with low and high planned labor consumption, the use of universal production station is the most advantageous. For such a solution, the degree of utilization of the available working time of production stations is also the highest. It was also found that the principles of scheduling production orders affect the effectiveness of the production system. The best results were obtained for the production schedule, where the sequence of production orders was established from the lowest planned time of resource loading.","PeriodicalId":48763,"journal":{"name":"Advances in Production Engineering & Management","volume":"11 1","pages":""},"PeriodicalIF":3.6,"publicationDate":"2020-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89082403","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 behaviour and functioning of these systems cannot be predicted with certainty as they belong to a group of probable determinate structures. Generally, if we wanted to know precisely the behaviour of this condition in advance, we would have to be able to describe them mathematically or observe the action of the system on a real object. By applying discrete event simulation software, we realize the development of environmentally friendly products and using the simulation, we gain the certainty that the planned tasks can be implemented in a given time frame, while the simulation of the production process can help to clearly clarify and better understand the processes. To choose the optimal manufacturing ways of cleaning the fabrics component from waste tyres, we used the Witness discrete event simulation software to determine the usability and time occupancy of individual machines in the production of new fabric-based material. We simulated the ultrasonic method of cleaning the fabrics component from waste tyres and the subsequent creation of the test specimen. After the simulation, the obtained data can be used by a selection of type and number of machines and auxiliary equipment, by numbers of tools and fixtures, and by numbers of transport equipment. Obtained results bring the best layout of the workplace, the optimal dose of input materials and resources used in production. We have identified bottlenecks in the machines with long waiting times. The research priority was to reduce bottlenecks and increase the effectiveness of the entire of production line.","PeriodicalId":48763,"journal":{"name":"Advances in Production Engineering & Management","volume":"1 1","pages":""},"PeriodicalIF":3.6,"publicationDate":"2020-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90121983","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 ConVRP is an extension of the VRP, considering customer satisfaction through consistent service. The consistency may be based on time or on the vehicle that offers the service. This paper proposes a novel mathematical model that allows solving the ConVRP for several companies for which visits to the customers need to be from the same service provider (namely, the same vehicle and driver). The efficiency of the model is tested on structured instances by changing customer distribution (uniform or clustered), depot location, and arrival time to the customer and re‐ moving certain constraints to see if they affect the performance of the objective function. The mathematical model is flexible and could be adapted to any characteristic of instances. The model was devel‐ oped in the AMPL programming language and solved with the solvers CPLEX and Gurobi. The results are promising based on the efficiency of the proposed method at solving the problem. This paper proposes a mathematical mixed‐integer linear programming model to solve the ConVRP. The proposed model can determine the total travel time of a vehicle fleet for a certain number of specific days, which routes should be taken by each vehicle per day, and the vehicles' arrival time for each customer. The mathematical model was tested on structured instances by analyzing changes to aspects such as customer distribution (uniform or clustered), depot loca‐ tion, arrival time at the customer, and removing certain constraints that affect the performance of the objective function. The model was developed in the AMPL programming language and solved with the solvers CPLEX and Gurobi. Although a mathematical model for the ConVRP at‐ tracts growing attention due to the few studies related to the problem. The mathematical struc‐ ture of the model is novel, and to the best of the author's knowledge, this is the first time a model for the ConVRP solves real and structured instances for companies that provide a consistent service over time, such as courier companies, elderly care service companies, and cleaning sec‐ tors, under realistic constraints.","PeriodicalId":48763,"journal":{"name":"Advances in Production Engineering & Management","volume":"27 1","pages":""},"PeriodicalIF":3.6,"publicationDate":"2020-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85781809","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}

Initially, each quality response was represented by a pentagon membership function. Then, the combination of optimal factor levels was obtained for each response replicate. Those optimal combinations were then used to construct pentagon regression models for each response. A pentagon fuzzy optimization model was formu‐ lated and solved to determine the combination of optimal factor levels at each element of pentagon response’s fuzzy number. Two real case studies, i.e. wire‐ electrical discharge machining and sputtering process, were provided for illustration. Optimal results of the two case studies revealed that the pro‐ posed procedure effectively optimized performance under uncertainty and provided larger improvement in multiple quality characteristics. In conclu‐ sion, the proposed procedure may enhance the process engineer’s knowledge about effects of uncertainty on process/product performance and help practi‐ tioners decide the proper adjustments of factor levels in order to enhance performance of electrical discharge machining and sputtering process. © 2020 CPE, University of Maribor.

As cavitation highly contributes to deteriorating the performance of the pump, anti‐cavitation performance is one of its design specifications. To clarify the cavitation evolu‐ tion at the tongue of the volute of a centrifugal pump at overload conditions and its influence on the flow field in the impeller, numerical simulation with ANSYS CFD and a hydraulic test were conducted on a volute pump at several flow rates above optimal value. The cavity distribution and the blade loading distribution were analyzed. And the characteristics of the pressure fluctuation of the monitoring points located in volute casing were obtained and compared with each other. Results showed that cavitation may first emerge at the tongue rather than the impeller inlet at overload conditions. The alternative stress resulting from periodical radial force increases obviously as the extent of cavitation at the tongue. Meanwhile, the mean cavity length grows as each blade comes close to the tongue, and causes a decrease in performance be‐ cause of a reduction or closure of flow passages. The pressure pulsation in the volute is consistent with the blade passing frequency whether cavitation occurs or not, while the pulsation intensity increases obviously after cavita‐ tion inception. From the first section to the eighth section of volute, the pulsa‐ tion intensity of impeller outlet decreases gradually. The results are then compared to provide a reference for the optimum design of the anti‐cavitation performance of centrifugal pump. © 2020 CPE, University of Maribor.

The optimal equilibrium results are compared in different scenarios, namely the retailer with no be‐ havioural preference, with single‐behavioural preference and with the two behavioural preferences. Although previous literatures have proven that overconfidence or fairness concern has a negative influence on retailer, we find that the retailer always benefits from these two behavioural preferences, whether it is retail price, sales effort or utility. This is because when the over‐ confident degree is within a reasonable range, overconfidence and fairness concern have a positive influence on retailer's decision‐making, and when the overconfident degree is high, the fairness concern preference can suppress the adverse effects caused by overconfidence. Compared with the preference of fairness concern, the overconfident preference plays a leading role in supply chain performance, which mainly manifests in retailer’s decisions, utility and manufacturer profit. Moreover, the wholesale price and profit of the rational manufacturer may become worsen due to the fairness concern of retailer. © 2020 CPE, University of Maribor.

The aim of the research is to determine the appropriateness of using simulation tool for (re)setting time standards for manual assembly tasks. An avatar in the simulation model performs sequenc‐ es of tasks with a handling mass of up to 20.5 kg. The individual times ob‐ tained from the simulation model were analysed and compared with several time prediction methods and validated in laboratory environment. An analy‐ sis of the influence of different load parameters on the total time was also performed. Dependency is mostly linear, so from the practitioner point of view, we can predict with reasonable certainty the total time for any sequence of manual assembly tasks for every size and mass of the box. Based on the results we can confirm that simulation tool JACK is suitable not only for ergo‐ nomic analyses but also for setting time standards for the workers.

This paper focuses on two types of incentives that a manufacturer may provide to retailers: customer satisfaction index bonus (CSI bonus) and customer satisfaction assistance, and studies the optimal customer satisfaction incentive plan of the manufac‐ turer when duopoly retailers adopt Cournot or collusion game. By comparing the equilibrium of the two games, we conducted a preference analysis of both the manufacturer and the retailers. The results showed that no matter what kind of games the duopoly retailers take, the manufacturer will provide cus‐ tomer satisfaction assistance to the retailers to increase the customer satis‐ faction. However, if the duopoly retailers take Cournot behaviour, only when the wholesale price is greater than the threshold, the manufacturer will pro‐ vide the retailers with customer satisfaction index bonus. The manufacturer always prefers to Cournot behaviour, and the retailers always prefer to collu‐ sion behaviour. In addition, this paper also investigated the effect of custom‐ er satisfaction incentives on the manufacturer, and found that it will help the manufacturer obtain more demand and higher profits. © 2020 CPE, University of Maribor.
