Manufacturing firms operating in today’s competitive global markets must continuously find the appropriate manufacturing scheme and strategies to effectively meet customer needs for various types of quality of merchandise under the constraints of short order lead-time and limited in-house capacity. Inspired by the offering of a decision-making model to aid smooth manufacturers’ operations, this study builds an analytical model to expose the influence of the outsourcing of common parts, postponement policies, overtime options, and random scrapped items on the optimal replenishment decision and various crucial system performance indices of the multiproduct problem. A two-stage fabrication scheme is presented to handle the products’ commonality and the uptime-reduced strategies to satisfy the short amount of time before the due dates of customers’ orders. A screening process helps identify and remove faulty items to ensure the finished lot’s anticipated quality. Mathematical derivation assists us in finding the manufacturing relevant total cost function. The differential calculus helps optimize the cost function and determine the optimal stock-replenishing rotation cycle policy. Lastly, a simulated numerical illustration helps validate our research result’s applicability and demonstrate the model’s capability to disclose the crucial managerial insights and facilitate manufacturing-relevant decision making.

<p>The <em>Hybrid Entropy</em>-TOPSIS method is a combination of two methods, <em>Entropy</em> and <em>TOPSIS</em>. The combination of the two methods is used in the decision-making model to improve the quality of a decision. In this research, the <em>Hybrid Entropy</em>-TOPSIS method was applied to determine the ideal contraceptive tool based on the acceptor criteria. Entropy is a method of weighted criteria, while TOPSIS is a method of decision making through the alternative ranking process based on weighted criteria. The criteria are factors which influence to <em>Keluarga Berencana</em> acceptors for selecting contraceptives. The used criteria in this research were the age, blood pressure, menstrual cycle, the use of contraceptives, and the cost. While the Alternative is contraceptive tool itself. The selected alternatives here were Pill, Injection, Condoms, Implant, IUD and MOP / MOW. Based on the results of the questionnaire data and the simulation, it was obtained that pill and implants has the highest ranking and they indicated that pill and implants as an alternative selection of the ideal contraceptives.</p>

<p><strong>Introduction</strong></p><p>Every patient has the right to refuse treatment and, or transport (RTT) to hospital (1). The National Ambulance Service (NAS) has operated under a clinical guidance document that requires an assessment of patient capacity and a baseline amount of data to be gathered on every patient to facilitate the patient making an informed decision (2,3). An increase in the rate of non-conveyance of patients and refusal to travel calls as well as an increasing number of complaints prompted a quality improvement initiative based on improving and facilitating a shared decision-making model.</p><p><strong>Aim</strong></p><p>For patients who RTT, to establish a baseline quality of information collected and recorded on a Patient Care Report.</p><p><strong>Methods</strong></p><p>All NAS incidents closed with a refusal of treatment or transport, from 1<sup>st</sup> Jan 2017 to 9<sup>th</sup> November 2017 were identified from National Emergency Operation Centre (NEOC).

Abstract The contribution sets simple mathematic models describing and explaining the way of behavior of various types of investors (the private and institutionalized ones). The models come from the cardinal utility theory which is used for explaining the connection between the subjective relationship towards risk and some pathologic phenomenon of finance theory (for example the moral hazard question of institutionalized investors) and takes into account the decision making of both ordinary people and professional investors. A reliable estimate of the economic surroundings where the investment should run contributes significantly to a quality of the particular investment decisions. The article contributes to a quality of the investment decision by the original and primary approach to pricing information that lowers the uncertainty in occurrences of the relevant scenarios of the project’s development. At the conclusion there is shown how the shift of the decision breaking point shapes the amount of the acceptable price of the information.

Hierarchy Process

A number of factors must be considered when selecting a convention site. Typically, most selections are based on the decision makers’ knowledge and experience, which may lead to biased decisions based on the decision makers’ subjective judgment. This study establishes decision-making evaluation factors and attributes for convention site selection based on a literature review. After surveying experts’ opinions using questionnaires, we employed the fuzzy analytic hierarchy process (FAHP) to analyze the weighting of the factors and attributes. The results show that of the five evaluation factors, site environment is the most important, followed by meeting and accommodation facilities, local support, extraconference opportunities, and costs. Additionally, the five most important attributes among the 20 evaluation attributes are the suitability of convention facilities, suitability and quality of local infrastructure, climate, city image, and political conflict or terrorist threats.

The Cost

Much of the health system’s avoidable spending may be driven by doctors’ decision making. Past studies demonstrated potentially consequential and costly inconsistencies between the actual decisions that clinicians make in daily practice and optimal evidence-based decisions. This commentary examines the “best practices regimen” through the lens of the quality measurement movement.  Although quality measures have proliferated via public reporting and pay-for-performance programs, evidence for their impact on quality of care is scant; the cost of care has continued to rise; and the environment for clinical decisions may not have improved. Naturalistic decision making offers a compelling alternative conceptual frame for quality measurement. An alternative quality measurement system could build on insights from naturalistic decision making to optimize doctors’ and patients’ joint decisions, improve patients’ health outcomes, and perhaps slow the growth of health care spending in the future.

Purpose – The purpose of this paper is to explore consumer decision-making factors related to purchases of licensed merchandise, while focussing on how consumers’ identification with the 2009 World Games (WG), perceptions of quality and attitudes toward collecting, affect the decision-making model with regards to purchasing intention. Design/methodology/approach – The research model is based on the study of Kwak and Kang (2009), but also includes an assessment of consumers’ collecting attitudes. A purposive sampling method was adopted and data were collected from 1,985 valid samples via questionnaire surveys during the 2009 WG in Kaohsiung, Taiwan. Structural equation modeling was used to test the decision-making model presented in this study. Findings – The results reveal that consumers’ intentions with respect to purchasing licensed merchandise are influenced most by their attitudes toward collecting, followed by the perceived quality of the merchandise. The findings also suggest that the greater the perceived quality of licensed merchandise, the more positive the consumer attitude toward collecting. Lastly, the study finds no direct effect between respondent WG identification and intention to purchase licensed merchandise. Research limitations/implications – An exploratory concept proposed in this study, WG identification, is quite different from either event or place identification. In this study, due to its influence on at least two other relationships, the effects of one's attitude toward collecting prove to be much more complicated than the previous literature suggests. Since all data were collected in Taiwan, the research findings may have been influenced by particular local cultural and political factors, and therefore might not be well informed by inferences drawn from western populations. Practical implications – It was found that emphasizing the collectability of licensed merchandise is the most effective strategy for increasing consumer purchasing intention and promoting sales of merchandise at similar international events and competitions. This finding should encourage those interested in increasing consumers’ purchasing intention to pay more attention to the importance of licensed commemorative merchandise. Originality/value – Due to a lack of first-hand data on the consumption of licensed merchandise at major international events and competitions, little direct empirical research has been done in Taiwan. This study is the first attempt to explore this issue.

The paper provides a multiple-experts Fuzzy-TOPSIS decision-making model for the selection among maintenance contractors based on the quality of tendering documents. The study introduces a set of selection criteria utilizing benefit and cost criteria from literature. The proposed model aggregates subjective linguistic assessments of multiple experts that express their opinions on the degree of importance of criteria and allows multiple decisionmakers to evaluate the compliance of contractors’ documents. For a case study, the model is applied to select among contractors tendering to maintain the heavy-duty cranes of an international steel company from literature. Several decision-making scenarios are investigated, and major changes in the final decision are observed. The changes in obtained results illustrate the need to better address uncertainties in rating and tendering an overqualified contractor at a higher cost.

Due to the increasing number of people traveling by air, the passenger flow at the airport is increasing, and the problem of passenger drop-off and pickup has a huge impact on urban traffic. The difficulty of taking a taxi at the airport is still a hot issue in the society. Aiming at the problem of optimizing the allocation of taxi resource, this paper is based on the cost-benefit analysis method to determine the factors that affect the taxi driver’s decision-making. The mathematical methods such as function equation, BP neural network algorithm, and queuing theory were used to establish a complete decision-making model for taxi drivers and an optimization model of dispatching efficiency at the airport. A conclusion has been drawn that the allocation of airport taxi resource should be arranged closely related to drivers’ revenue and the layout of airport line.
