Abstract

Purpose

The aim of this paper is to present a method for finding the optimum balance between sequence-dependent setup costs, holding costs, delivery costs and delay penalties in an integrated production–distribution system with lot sizing decisions.

Design/methodology/approach

Two mixed integer linear programming models and an optimality property are proposed for the problem. Since the problem is NP-hard, a genetic algorithm reinforced with a heuristic is developed for solving the model in large-scale settings. The algorithm parameters are tuned using the Taguchi method.

Findings

The results obtained on randomly generated instances reveal a performance advantage for the proposed algorithm; it is shown that lot sizing can reduce the average cost of the supply chain up to 11.8%. Furthermore, the effects of different parameters and factors of the proposed model on supply chain costs are examined through a sensitivity analysis.

Originality/value

Although integrated production and distribution scheduling in make-to-order industries has received a great deal of attention from researchers, most researchers in this area have treated each order as a job processed in an uninterrupted time interval, and no temporary holding costs are assumed. Even among the few studies where temporary holding costs are taken into consideration, none has examined the effect of splitting an order at the production stage (lot sizing) and the possibility of reducing costs through splitting. The present study is the first to take holding costs into consideration while incorporating lot sizing decisions in the operational production and distribution problem.

Abstract

Purpose

The purpose of this paper is to propose the data envelopment analysis (DEA) model that can be used as binary-valued data. Often the basic DEA models were developed by assuming that all of the data are non-negative. However, there are situations where all data are binary. As an example, the information on many diseases in health care is binary data. The existence of binary data in traditional DEA models may change the behavior of the production possibility set (PPS). This study defines a binary summation operator, expresses the modified principles and introduces the extracted PPS of axioms. Furthermore, this study proposes a binary integer programming of DEA (BIP-DEA) for assessing the efficiency scores to use as an alternate tool in prediction.

Design/methodology/approach

In this study, the extracted PPS of modified axioms and the BIP-DEA model for assessing the efficiency score is proposed.

Findings

The binary integer model was proposed to eliminate the challenges of the binary-value data in DEA.

Originality/value

The importance of the proposed model for many fields including the health-care industry is that it can predict the occurrence or non-occurrence of the events, using binary data. This model has been applied to evaluate the most important risk factors for stroke disease and mechanical disorders. The targets set by this model can help to diagnose earlier the disease and increase the patients’ chances of recovery.

Abstract

Purpose

A stroke is a serious, life-threatening condition that occurs when the blood supply to a part of the brain is cut off. The earlier a stroke is treated, the less damage is likely to occur. One of the methods that can lead to faster treatment is timely and accurate prediction and diagnosis. This paper aims to compare the binary integer programming-data envelopment analysis (BIP-DEA) model and the logistic regression (LR) model for diagnosing and predicting the occurrence of stroke in Iran.

Design/methodology/approach

In this study, two algorithms of the BIP-DEA and LR methods were introduced and key risk factors leading to stroke were extracted.

Findings

The study population consisted of 2,100 samples (patients) divided into six subsamples of different sizes. The classification table of each algorithm showed that the BIP-DEA model had more reliable results than the LR for the small data size. After running each algorithm, the BIP-DEA and LR algorithms identified eight and five factors as more effective risk factors and causes of stroke, respectively. Finally, predictive models using the important risk factors were proposed.

Originality/value

The main objective of this study is to provide the integrated BIP-DEA algorithm as a fast, easy and suitable tool for evaluation and prediction. In fact, the BIP-DEA algorithm can be used as an alternative tool to the LR model when the sample size is small. These algorithms can be used in various fields, including the health-care industry, to predict and prevent various diseases before the patient’s condition becomes more dangerous.

Abstract

Purpose

This study aims to examine whether citizens of non-Muslim countries accept products with a “halal” logo. In the era of globalization, one of the most crucial issues for Muslim travelers is reliable halal foods when visiting non-Muslim countries. If people in non-Muslim countries accept imported products containing halal certification logos, and such products are readily available in shops, this issue could be substantially improved.

Design/methodology/approach

Malaysia and Japan were selected as Muslim and non-Muslim countries, respectively, to conduct a choice experiment (CE) for 656 non-Muslim subjects, and estimated willingness to pay (WTP) for mineral water with and without the halal logo. A random parameter logit model was used for estimation.

Findings

The difference between the WTP for mineral water with and without the halal logo was ¥5; however, the associated coefficient is not statistically significant. This implies that the halal logo has no impact on non-Muslim subjects’ purchasing behavior. From this, we can infer that the halal products with certification logo would be accepted in Japanese shops, which may foster foreign Muslim visits.

Research limitations/implications

As the results are based on a couple of countries (Malaysia and Japan) and only one product (mineral water), further investigation using other products in different countries would be necessary. However, as suggested in the main text, the results enjoy a degree of generalizability.

Originality/value

The results of this study support the possibility of circulating halal products in non-Muslim countries and thus promoting Muslim travel abroad. No such study has examined this issue using CE.

Abstract

Purpose

Developing green consumption, organic and green meat and poultry consumption have been increased recently. The purpose of this paper is to investigate the effect of food’s sensory characteristics (e.g. organic food beliefs) and non-food factors (e.g. price transparency) on consumers’ green purchase behavior. So, according to the moderating role of price transparency, affecting factors on green chicken purchase intention and behavior are examined.

Design/methodology/approach

Evaluating the model, the authors used measures from previous research. The authors distributed questionnaire in four chain stores in four different geographical regions in Tehran. The structural model and relations were examined by using Smart PLS 2.0 software to simultaneously estimate the measurement and structural models.

Findings

Structural equation analysis revealed that level of trust, consumer’s organic food beliefs and perceived environmental responsibility have positive impact on green purchase intention. Also price transparency moderator role confirmed that moderators can affect consumers’ actual behavior.

Research limitations/implications

As our sample was just from Tehran, the research results may lack generalizability to all people in Iran. Therefore, future researchers are encouraged to retest the proposed model in other cities and also in other countries with different level of economic development.

Practical implications

This paper includes suggestions for managers and producers to develop green food products consumption especially green chicken. Also it has implications for spreading out green consumption among people with high environmental involvement.

Originality/value

Despite conducted research, the moderating role of price transparency has been used only rarely to investigate consumers’ green purchase behavior.

Abstract

Purpose

The purpose of the study is to investigate the effect of augmented reality (AR) characteristics in packaging on perceived value and consumer behavioral intentions such as purchase intention and pay more in traditional Iranian nougat GAZ packaging.

Design/methodology/approach

The statistical population was the 550 customers bought traditional Iranian nougat GAZ. Sampling method was simple random sampling. Questionnaire had been chosen for collecting data. In total, 236 customers filled in questionnaires. Research model tested by structural equation modeling method and by using SPSS and PLS software.

Findings

The finding considered the characteristics of AR packaging which include interactivity, informativeness, enjoyment and usefulness have a positive effect on the dimensions of the perceived value, hedonic and utilitarian value. In the same way hedonic and utilitarian value had positive effects on the consumer behavior, purchase intention and willingness to pay more.

Originality/value

These results help managers to use AR characteristics to improve the interaction between customers and product and sell their products.

Abstract

Purpose

The purpose of this paper is organized as follows. Section 2 reviews the literature on the subject matter, focusing on western economic literature and the Islamic economic paradigm, including the Quran, Sunnah, jurisprudence and Islamic philosophy thinking, to illustrate the origins of the Islamic approach to monetary systems. The money interest rate and its studies are explained, and the role of money and credit in the production function is considered. Then, it is shown that money maintains the demand for money in the overlapping generation model, as well as the consumption behavior of households. It is followed by an explanation of general Pareto optimality and the role of the money interest rate in inefficiency and nonoptimality for households and firms. Finally, Section 4 concludes the paper.

Design/methodology/approach

This paper studies the effects of money issuance and bank creation on Pareto optimality. In explaining the origins of the Islamic approach to monetary systems, the literature review, it focuses on western economics’ literature and Islamic economics paradigms such as the Quran, sunnah, jurisprudence and Islamic philosophy thinking. In modeling section, the authors show how banks’ fractional reserve credit is profitable. The authors also examine how the introduction of the money interest rate can change the Pareto optimality. In this regard, the comparison between two situations, namely, financing by the stock of money and borrowing in the credit market, indicates that welfare is reduced by the creation system and is inefficient (or nonoptimal). The result is that no money and no credits are created. The provision of this system compensates money by increasing the real money supply or deflation. To ensure Pareto optimality, it has been proven in the field of microfoundation that there should be no fixed money contracts and no money interest rates. It is necessary that the interest rate on consumption credit is zero or Qarz-al-Hasna is broken. Moreover, profit sharing is offered in the production sector.

Findings

As a result, the authors proved mathematically that the money interest rate must be zero to ensure productivity and Pareto optimality. On the other hand, the introduction of money or credit through loanable money leads to inefficiency, both in production and households and in the general equilibrium. The inflation generated by the credit system stimulates the change in the price level and perpetuates this inefficiency. Thus, if the authors want to return to the optimality condition, the interest rate on consumption credit must be zero or Qarz-al-Hasna is breached. However, the behavior of the fractional banking system and the credit mechanism teaches us that the money interest rate is an integral part of credit and loanable funds. Thus, the elimination of the money interest rate from the banking system without bank creation is implausible. Finally, to ensure Pareto optimality, it has been mathematically proven in the field of microfoundation that there should be no fixed money contracts and no money interest rate. It is necessary that the interest rate on consumption credit is zero, or Qarz-al-Hasna is broken. Moreover, profit sharing is offered in the production sector. The result is that no money and credit are created. The provision of this system compensates money by increasing the real money supply or deflation.

Originality/value

The capitalist theory of the definition of interest plays a decisive role in economic science. In this context, the authors are dealing with different vocabularies and terms for the interest rate. These different vocabularies have their origin in the different economic situations and especially determine the thinking of the schools. Because of the relationship between future and spot, the authors have to transform the variable “level” into the variable “interest rate” in the dynamic space. Finally, the exact explanations for the movement and evaluation of the economy are revealed by the correlation of the different interest rates.

Abstract

Purpose

Over the past few decades, a large number of research studies have examined tourism. However, studies that examine halal tourism are still limited. Therefore, the purpose of this study is to conduct a bibliometric analysis related to halal tourism based on the results of empirical research studies that have been published.

Design/methodology/approach

The approach in this study uses a systematic literature review related to halal tourism as a reference in “Article Title, Abstract and Keywords” based on the Scopus database from 1997 to 2023. The analysis was conducted on January 8, 2023. The data that has been collected will be analyzed bibliometrically using VOSviewer.

Findings

The research findings show that research related to halal tourism is still relatively rare, especially in countries/locations where the majority of the population is non-Muslim. This can be seen from the majority of previous studies conducted in Muslim-majority countries/locations, such as Malaysia and Indonesia. Future research should be conducted in countries/locations where the majority of the population is non-Muslim.

Research limitations/implications

This study relies on research in halal tourism literature in the Scopus database. Future studies can combine with the Web of Science database to expand generalization.

Practical implications

The results of this study include implications for managing and developing sustainable halal tourism in the future for practitioners.

Social implications

The results of this study provide a strategic perspective to practitioners and society in general to find out how the concept of sustainable halal tourism development in the future is in accordance with Islamic sharia.

Originality/value

Research related to halal tourism is currently starting to develop in various countries, both with a majority Muslim and non-Muslim population. In addition, until now research related to halal tourism is still limited literature that discusses.
