PurposeEquipment reliability significantly impacts productivity, and in order to obtain high equipment reliability and productivity, maintenance and production decision should be made simultaneously to keep manufacturing system healthy. The purpose of this paper is to investigate the joint optimization of equipment maintenance and production decision fork-out-of-nsystem equipment with attenuation of product quality and to explore the impact of maintenance on the production and cost control for manufacturers.Design/methodology/approachA multi-period Markov chain model fork-out-of-nsystem equipment is set up based on the assumption that the deterioration of equipment is a pure birth process. Then, the maintenance cost, setup cost, inventory holding cost, shortage cost, production cost and the quality cost are analyzed with the uncertain demand and the attenuation of product quality stemmed from equipment deterioration. The total lowest cost per unit time and its specific calculation method are presented. Finally, the robustness and flexibility of the method are verified by a numerical example and the effects of equipment deterioration intensity and attenuation of product quality are analyzed.FindingsThe result shows that the joint decision model could not only satisfy the uncertain demand with low cost and strong robustness but also make the output products high quality level. In addition, the attenuation of product quality would influence the equipment maintenance and production decision and leads to the production waste and increases the operation cost greatly.Originality/valueImplications derived from this study can help production maintenance managers and reliability engineers adequately select maintenance policy to improve the equipment efficiency and productivity with high quality level at a relatively low cost.

Purpose The purpose of this paper is to analyse the evolution of top management’s understanding of product quality in Bulgaria since the end of communism. The study examines three specific areas: top management’s understanding of the term “quality”; top management’s understanding of the relationship between quality and business performance; and top management’s understanding of the impact of job position on quality. Design/methodology/approach The paper relies on a quantitative research approach by using data from a survey of 186 companies in Bulgaria. Findings The paper suggests that senior managers in Bulgaria continue to base their understanding of “quality” on a single approach (*a characteristic of the communist era), with the product-based and the user-based approaches currently being the two most common ones. At the same time, surprisingly enough, this study claims that senior management in Bulgaria is currently well aware of the importance of quality as a dimension of firm’s competitiveness, and is also highly conscious of its roles’ impact on product quality. Research limitations/implications The results of this study are exclusively based on the case of Bulgaria and must be treated with caution in the case of other former communist states from the Central and Eastern Europe (CEE) region. Practical implications This paper has relevance for both managers and companies doing business in Eastern Europe. Originality/value This is the first paper to provide detailed analysis of the evolution of the understanding of “product quality” in CEE since the end of communism. Moreover, this paper applies, for the first time, Garvin’s five approaches to defining quality within a practical context.

The Impact

Web Real-Time Communication (WebRTC) combines a set of standards and technologies to enable high-quality audio, video, and auxiliary data exchange in web browsers and mobile applications. It enables peer-to-peer multimedia sessions over IP networks without the need for additional plugins. The Opus codec, which is deployed as the default audio codec for speech and music streaming in WebRTC, supports a wide range of bitrates. This range of bitrates covers narrowband, wideband, and super-wideband up to fullband bandwidths. Users of IP-based telephony always demand high-quality audio. In addition to users’ expectation, their emotional state, content type, and many other psychological factors; network quality of service; and distortions introduced at the end terminals could determine their quality of experience. To measure the quality experienced by the end user for voice transmission service, the E-model standardized in the ITU-T Rec. G.107 (a narrowband version), ITU-T Rec. G.107.1 (a wideband version), and the most recent ITU-T Rec. G.107.2 extension for the super-wideband E-model can be used. In this work, we present a quality of experience model built on the E-model to measure the impact of coding and packet loss to assess the quality perceived by the end user in WebRTC speech applications. Based on the computed Mean Opinion Score, a real-time adaptive codec parameter switching mechanism is used to switch to the most optimum codec bitrate under the present network conditions. We present the evaluation results to show the effectiveness of the proposed approach when compared with the default codec configuration in WebRTC.

Quality Of Products

In the world, product quality has long been one of the major instruments for ensuring the economic development of companies. Achieving high quality parameters, in turn, is an important part of the economic strategy of any success-oriented business organization. The article is aimed at developing directions for improving products of PJSC «Beer and Non-Alcoholic Plant «Radomyshl». The object of the research is the quality of beer produced by PJSC «Beer and Non-Alcoholic Plant «Radomyshl». The assessment of the quality level of the selected product in accordance with the requirements of DSTU 3888:2015 was carried out using the following groups of indicators: microbiological, organoleptic and physic-chemical. The process of assessing the product quality parameters is presented, which consists of seven consecutive stages and is carried out throughout the product life cycle. The factors under the influence of which the quality of products are formed and which may cause deviation from the specified quality parameters are analyzed and structured. The defects that appear due to these factors have been identified. The basis for improving the quality of products is primarily a thorough study of changes in demand for the business organization products. Three groups of measures are singled out, with the help of which one can achieve the desired level of product quality, namely: technological, organizational and socio-economic. A complex of priority measures to improve the quality of products of PJSC «Beer and Non-Alcoholic Plant «Radomyshl» is proposed. The element of scientific novelty is the development of an algorithm for the implementation of measures to improve the quality of products. During the implementation of measures to improve the quality, it is necessary to carry out systematic monitoring and generate reports on the implementation of the project in order to make possible an adjustment of the final result.

Purpose Using a unique sample of about 563,000 competitively bid municipal revenue bonds with financial advisors issued during the period 1998–2012, the purpose of this paper is to examine the role and influence of financial advisor quality in the municipal bond market. Design/methodology/approach The authors use a sample of about 563,000 competitively bid municipal revenue bonds with financial advisors issued during the period 1998–2012. The authors estimate a selection model where the authors identify the factors leading to the selection of a high-quality financial advisor. The authors then, using the inverse mills ratio from the first regression, estimate the association of high-quality advisor (and other factors) with the cost of borrowing. Findings The results suggest that high-quality financial advisors provide a credible signal to market participants about issue and issuer quality. This signal translates to a greater number of bids for issues that use high-quality financial advisors, resulting in improved liquidity and lower borrowing costs for these issues. The results also show that the beneficial effects obtained by using higher quality financial advisors are prevalent across all categories of issues such as for refunding and non-refunding issues, and for both insured and non-insured issues. The benefits are also generally observed for issues of most size categories. The results also suggest that the passage of the Dodd–Frank Act requiring mandatory registration of financial advisors and enhanced scrutiny has only increased the benefits to issuers from using higher quality financial advisors. Originality/value This paper differs from previous research in several important ways. First, the study is, to the authors’ knowledge, the first study that explores the relationship between financial advisor quality and liquidity in the municipal sector. The authors show using higher quality financial advisors enhances liquidity for the issues by attracting a significantly large number of bids. Second, the sample is exclusively comprised of competitively bid revenue issues all of which rely on financial advisors. This enables us to examine more unambiguously the influence of financial advisor quality, without the confounding effects of issues without financial advisors. Third, time coverage (1998–2012) and size of the sample (roughly 563,000 bond issues) enables us to conduct varied sub-sample analyses with greater power since the resulting sub-sample partitions themselves are of very large size. This provides better and additional insights into the role of financial advisor quality. The more current data when compared to prior research enables us to examine the impact of financial advisor quality inter-temporally with special attention devoted to the period after passage of the Dodd–Frank Act.

The Impact

Purpose The purpose of this paper is to explore the impact of the cost of quality (COQ) expenditure allocations on a capacitated supply chain (SC) network. Design/methodology/approach This paper proposes a non-linear optimization model which integrates the opportunity cost (OC) (i.e. customer satisfaction cost), into the COQ with consideration of the QL in the supply chain network design decisions. In addition, it examines the effect of considering an investment at each SC echelon to ensure the best overall QL. A numerical example is presented to illustrate the behavior of the model. Findings The results show how the QL, COQ and facility location decisions change when incorporating the OC, investments and transportation costs into the SC model. Originality/value The novelty of this paper is that it considers the effect of OC, investment at each echelon and transportation costs on SC design by minimizing the overall spending on the COQ. These issues have not been explored, and for that reason, this paper contributes to the understanding of the critical factors that optimizes the SC COQ.

Subject area The subject areas are strategic management, international marketing business-to-business marketing. Study level/applicability The study is applicable to undergraduate and postgraduate courses. Case overview Dalmec Industries Manipulators India Pvt. Ltd. was incorporated in 2011 as a private limited company under the Companies Act, 1956. The company was formed to carry on importing machinery and distributing it to the clients. This case focuses on the dilemma faced by the company: whether it should establish a manufacturing unit in India or continue with the current operation procedures. Dalmec has faced various problems in India regarding local players, low-cost material handling equipment and the nascent stage of material handling industry. In Europe and the Middle East, the industries are more focused on safety standards and provide high quality material handling products to their workers, compared to the Indian industries. As local players in material handling sectors price their product very low, to compete with them with quality products is a major challenge for foreign companies. The company needed to build a strong and unique brand for non-European markets. In India, the material handling equipment market is crowded with local players. So, Dalmec needs to establish its reputation as a reliable partner and create a distinct identity. It has to create brand awareness among Indian companies and influence the decision makers of the corporates. The case discusses the impact of Make in India campaign on Dalmec and examines whether the Make in India initiative will prove helpful to Dalmec. Expected learning outcomes This study enables to familiarize students with the expansion strategy of a company; help students understand the international market entry strategies frequently used by multinationals to expand their business.; examine the feasibility of entering into emerging markets like India; and make students understand the relevance of the Make in India campaign for foreign corporate players.

The Impact

Purpose This paper aims to assess the impact of perceived effort related to packaging on overall product evaluations. Perceived effort, defined as the consumer’s perceptions of how much manufacturer effort that lies behind an offer, is assumed to contribute to evaluations by signaling unobservable characteristics of an offer. Design/methodology/approach Three between-subjects experiments were conducted with soft drink bottles, which were subject to variation in perceived effort. Findings The results show that perceived effort was positively associated with overall evaluations. The results also show that the impact of perceived effort was mediated by product quality perceptions, which indicates that effort signals quality. Originality/value Perceived effort has to date not been examined in the packaging literature. The present findings thus imply that models of packaging characteristics and their impact on consumers would benefit from including the effort aspect.
