Abstract

Unresolved construction dispute can be detrimental to project success. A systematic method to evaluate the seriousness of construction dispute of a construction project will assist management to take appropriate corrective actions. Evaluation of construction disputes requires an analysis on both the likelihood of occurrence and its impact, which are normally expressed by practitioners in linguistic terms. The application of classical discrete analysis will not be able to accommodate the fuzzy nature of this information. To determine how fuzzy sets theory can be applied to construction disputes evaluation (CDE), a fuzzy CDE model has been developed based on the knowledge extracted from practitioners in Hong Kong. The fuzzy CDE system consists of four components: dispute identification, dispute analysis; dispute evaluation; and dispute control. This paper describes the framework and operation of the fuzzy CDE system developed. The results indicate that CDE can be modelled by the fuzzy sets theory.

Abstract

Purpose

The starting point of this paper is the propositional model of conflict resolution which was presented and critically discussed in Lempp (2016). Based on this model, a software implementation, called ProCON, is introduced and applied to three scenarios. The purpose of the paper is to demonstrate how ProCON can be used by negotiators and to evaluate ProCON’s practical usefulness as an automated negotiation support system.

Design/methodology/approach

The propositional model is implemented as a computer program. The implementation consists of an input module to enter data about a negotiation situation, an output module to generate outputs (e.g. a list of all incompatible goal pairs or a graph displaying the compatibility relations between goals) and a queries module to run queries on particular aspects of a negotiation situation.

Findings

The author demonstrates how ProCON can be used to capture a simple two-party, non-iterative prisoner’s dilemma, applies ProCON to a contract negotiation between a supplier and a purchaser of goods, and uses it to model the negotiations between the Iranian and six Western governments over Iran’s nuclear enrichment and stockpiling capacities.

Research limitations/implications

A limitation of the current version of ProCON arises from the fact that the computational complexity of the underlying algorithm is EXPTIME (i.e. the computing time required to process information in ProCON grows exponentially with respect to the number of issues fed into the program). This means that computing time can be quite long for even relatively small negotiation scenarios.

Practical implications

The three case studies demonstrate how ProCON can provide support for negotiators in a wide range of multi-party, multi-issue negotiations. In particular, ProCON can be used to visualise the compatibility relations between parties’ goals, generate possible outcomes and solutions and evaluate solutions regarding the extent to which they satisfy the parties’ goals.

Originality/value

In contrast to standard game-theoretic models of negotiation, ProCON does not require users to provide data about their preferences across their goals. Consequently, it can operate in situations where no information about the parties’ goal preferences is available. Compared to game-theoretical models, ProCON represents a more general approach of looking at possible outcomes in the context of negotiations.

Abstract

Purpose

This paper seeks to analyse the content and implications of resolution 52/1 of the Commission on Narcotic Drugs of the United Nations (UN) titled “Promoting international cooperation in addressing the involvement of women and girls in drug trafficking, especially as couriers”.

Design/methodology/approach

Drawing on socio‐legal analysis and an extensive search of UN databases, the resolution is contextualised and the findings of the resulting report which examines the scale of women's participation in the global drug trade is summarised.

Findings

The article demonstrates that the data produced are unreliable as a measure of women's participation in the international drug trade.

Practical implications

It is argued that this resolution is weakened by lack of clarity about how gender ought to be mainstreamed in global drug control.

Originality/value

As the first resolution on women and girls' participation in the international drug trade, Resolution 52/1 is a significant step towards raising awareness and systematically accounting for their participation.

Abstract

Purpose

Drawing upon the elaboration likelihood model, this study aims to illuminate contradictory findings from previous research regarding the impact of positive and negative emotions, as well as promotions, on impulse buying (IB). Specifically, this study takes a two-faceted approach to IB, considering both affective IB and cognitive IB.

Design/methodology/approach

A proposed model of IB is tested using a mall intercept survey.

Findings

The findings provide evidence for the two-dimensional nature of IB. Cognitive and affective IB are affected differently by promotions and emotions, and in turn, have different impacts on cognitive dissonance (CD). Specifically, promotions have a positive effect only on cognitive IB, while positive emotions have a positive effect only on affective IB. Additionally, cognitive IB positively affects CD, while affective IB does not.

Research limitations/implications

Future research could explore different types of IB and unplanned purchases, consider the valence and arousal dimensions of emotions and examine how technological changes impact IB. Additionally, studying satisfaction as a mediator between IB and cognitive dissonance can contribute to the understanding of IB post-purchase outcomes.

Practical implications

By tailoring promotional techniques to cognitive IB and using positive emotions to stimulate affective IB, retailers can enhance the effectiveness of strategies. Furthermore, post-purchase strategies can be developed to reduce the negative effects of CD.

Originality/value

By exploring the different dimensions of IB and their relationships with CD, this study enhances our understanding of the underlying processes and mechanisms that drive consumer IB behavior during and after shopping trips.

Abstract

Purpose

Globalization in supply chain networks is urging manufacturing companies for the production of sustainable products with re-engineering technologies that offer competitive advantage in current market. However, the increasing sustainable illumes are influencing reverse logistics (RL) systems to analyze their impacts on economy, environment and society. Recently, China’s $62bn investment under the egis of China Pakistan Economic Corridor (CPEC), which comprises a number of infrastructure and energy projects is developing Pakistan as a part of “One Belt One Road” initiative. Accordingly, a substantial number of economical, ecological and social exercises will occur in closest future. The purpose of this paper is to investigate the impact of sustainable practices, i.e., environmental, economic and social sustainability on RL recovery options.

Design/methodology/approach

Sustainable concepts including environmental, economic and social and RL recovery options are extracted through extensive literature review. A number of researchers used a variety of methodologies for achieving their research objectives. However, the authors will be using a combination of VIsekriterijumska optimizacija i KOmpromisno Resenje (VIKOR) and grey relational analysis (GRA) technique under fuzzy environment in the case of CPEC.

Findings

Results show that waste management, impact on bio-diversity and economic growth are the most significant factors in designing sustainable RL recovery options. Moreover, remanufacture and reuse rank top among RL recovery options due their significant economic and environmental effects, whereas recycle and resell position last due to their high cost and cutting edge modern technologies.

Practical implications

Finally based on this model, it is possible for authorities to design a sustainable RL strategy for efficient operations in case of CPEC projects and other developing countries as well.

Originality/value

Negligible work has been done regarding sustainable modeling in RL strategies using a combination of VIKOR and GRA techniques subjected to fuzzy environment in the case of CPEC from perspective of developing country, i.e., Pakistan.

Abstract

Purpose

Enterprise resource planning (ERP) is assumed as a commonly used solution in order to provide an integrated view of core business processes, including product planning, manufacturing cost, delivery, marketing, sales, inventory management, shipping and payment. Selection and implementation of a suitable ERP solution are not assumed a trivial project because of the challenging nature of it, high costs, long-duration of installation and customization, as well as lack of successful benchmarking experiences. During the ERP projects, several risk factors threat the successful implementation of the project. These risk factors usually refer to different phases of the ERP projects including purchasing, pilot implementation, teaching, install, synchronizing, and movement from old systems toward new ones, initiation and utilization. These risk factors have dominant effects on each other. The purpose of this paper is to explore the hybrid reliability-based method is proposed to assess the risk factors of ERP solutions.

Design/methodology/approach

In this regard, the most important risk factors of ERP solutions are first determined. Then, the interactive relations of these factors are recognized using a graph based method, called interpretive structural modeling. The resultant network of relations between these factors initiates a new viewpoint toward the cause and effect relations among risk factors. Afterwards, a fuzzy fault tree analysis is proposed to calculate Failure Fuzzy Possibility (FFP) for the basic events of the fault tree leading to a quantitative evaluation of risk factors.

Findings

The whole proposed method is applied in a well-known Iranian foodservice distributor as a case study. The most impressive risk factors are identified, classified and prioritized. Moreover, the cause and effect diagram between the risk factors are identified. So, the ERP leader can plan a low-risk project and increase the chance of success.

Originality/value

According to the authors’ best knowledge, such approach was not reported before in the literature of ERP risk assessments.

Abstract

AFTER viewing the Messerschmitt Me. 110, one is impressed by the fact that here is an aeroplane provided with terrific striking power, but with practically no defensive armament or armour. The four machine‐guns and two cannon, tightly packed into the nose of the fuselage, provide heavy lire power, and contrast sharply with the single flexible machine gun supported on a primitive mount in the aft cockpit. A quickly detachable, external bomb rack designed to carry two bombs, apparently of the 500 lb. class, is provided for use on missions where attack of ground objectives, such as troop concentrations, would be the principal purpose.

Abstract

Purpose

Online reviews have shown important information that affects consumers’ online shopping behavior. However, little research has examined how they may influence consumers’ online impulse buying behavior. The purpose of this paper is to bring theoretical and empirical connections between them.

Design/methodology/approach

The framework of this study was tested on three popular online group shopping websites in China (ju.taobao.com, dianping.com, and meituan.com). An online survey with 315 participants who had experience using these websites was recruited to verify the effects of consumers’ perceived value from reading online reviews on urge to buy impulsively and impulse buying behavior.

Findings

The empirical findings show that consumers’ perceived utilitarian and hedonic value from reading online reviews enhance their browsing behavior. Browsing positively affects consumers’ urge to buy impulsively and finally affects their impulse buying behavior. Further, this study finds that consumers with high impulsiveness focus more on hedonic value of online reviews, whereas consumers with low impulsiveness put more emphasis on utilitarian value. Browsing demonstrates a stronger effect on urge to buy impulsively for consumers with high impulsiveness.

Originality/value

This study is one of the early studies to investigate the relationship between social influence (e.g. influence of online reviews) and impulse buying. It draws upon the perspectives of browsing and consumer’s perceived value from the literature. This research also considers consumer differences regarding the level of impulsiveness.

Abstract

This study used both qualitative and quantitative data to test hypotheses related to consumers’ motivations to engage in impulse buying. A grounded theory approach was used to develop hypotheses from in‐depth interviews. These hypotheses were tested by the collection and analysis of survey data. Data support the theory that impulse buying is a common method of product selection, in part, because the shopping act and impulsive product selection provide hedonic rewards. Further information‐processing overload confounds product selection, reinforcing the rewards to be obtained from alternative section heuristics, like impulse buying.
