Abstract

Purpose

The purpose of this paper is to develop a novel integrated supplier selection approach incorporating decision maker’s risk attitude using the artificial neural network (ANN), analytic hierarchy process (AHP) and technique for order of preference by similarity to ideal solution (TOPSIS) methods.

Design/methodology/approach

In the proposed approach, the ANN model is used to classify decision maker’s risk attitude; the fuzzy AHP method is used to determine the relative weights of evaluation criteria; and the fuzzy TOPSIS method is used to evaluate ratings of suppliers. Finally, experiments are conducted to verify the feasibility and efficiency of the proposed integrated approach.

Findings

Experiments results show that the proposed integrated approach is effective and efficient to help decision makers to select suitable suppliers according to their risk attitudes.

Originality/value

The aim of this paper is to develop a novel integrated supplier selection approach incorporating decision maker’s risk attitude using the ANN, AHP and TOPSIS methods. The decision maker’s risk attitude toward procurement transaction is originally considered in supplier selection process.

Abstract

Purpose

The paper aims to address how firms make strategic adjustment to the changing resource availability in different monetary policy conditions and how the stickiness of cost influences the strategic adjustment, and to dig out the major internal and industrial factors that influence the relationship between strategic change and monetary policy conditions.

Design/methodology/approach

The mechanism of how monetary policy affects strategic change is expounded by resource-based view and transaction cost theory. The balanced panel data of 422 companies of manufacturing industry listed in Chinese A share market before the end of 2003 from 2004-2013 are selected as sample to test the theoretic hypotheses.

Findings

It was found that looser monetary policy results in greater strategic change than the tighter one for the high adjustment cost. External capital dependence and industrial competition intensity strengthen the positive correlation between monetary policy condition and strategic change. Private firms are more susceptible to money supply condition change compared with state-owned enterprises. Companies tend to expand investment on fixed asset but to shrink investment on R & D and trademark in looser money supply condition.

Practical implications

Companies make bigger strategic adjustment in looser monetary policy condition for the greater availability of financial resources and lower market risk, but smaller adjustment in the tight one. However, owing to the sunk cost and the high adjustment cost, companies are not suggested to make aggressive strategic adjustment in the loose monetary conditions so as to avoid overcapacity and financial risk in tight monetary policy condition. For the policy-maker, as loose monetary policy cannot stimulate innovation but boost expansion on capacity, it is better to strengthen the resources configuration mechanism of monetary policy when making monetary policy.

Originality/value

This paper fulfils a theoretic gap to study the mechanism of how monetary policy influence corporate strategic resource reconfiguration via affecting the resource base of a company by combining resource-based view and transaction cost theory.

Abstract

We introduce the concepts of information, uncertainty information, systems and uncertainty systems, analyze the intension of these concepts, and point out the differences and connections among various concepts of systems. We put forward a mathematical method to research uncertainty systems and present a problem that can be solved with our method but cannot be solved with the interval analyzing method. Otherwise, from analyzing the purpose of introducing the concepts of information, uncertainty information, systems and uncertainty systems, we conclude that uncertainty information and uncertainty systems are among the most important subjects studied in scientific research, especially in applied research, both that being presently conducted and the abundance which is to come in the future.

Abstract

Purpose

Carbon emissions from gas flaring in the Nigerian oil and gas industry are both a national and international problem. Nigerian government policies to eliminate the problem 1960-2016 yielded little or no results. The Kyoto Protocol (KP) provides Clean Development Mechanism (CDM) as an international market-based mechanism to reducing global carbon emissions. Therefore, the purpose of this paper is to analytically highlight the potentials of CDM in eliminating carbon emissions in the Nigerian oil and gas industry.

Design/methodology/approach

This paper reviewed the historical background of Kyoto protocol, Nigerian Government policies to eliminating gas flaring in its oil and gas industry 1960-2016 and CDM projects in the industry. The effectiveness of the policies and CDM projects towards ending this problem were descriptively analysed.

Findings

Government policies towards eliminating gas flaring with its attendant carbon emissions appeared not to be yielding the desired results. However, projects registered under CDM in the industry looks effective in ending the problem.

Research limitations/implications

Therefore, the success recorded by CDM projects has the policy implication of encouraging Nigeria to engage on establishing more CDM projects that ostensibly proved effective in reducing CO2 emissions through gas flaring reductions in its oil and gas industry. Apparent effectiveness of studied CDM should provide a way forward for the country in eliminating gas flaring in its oil and gas industry which is also a global menace. Nigeria could achieve this by providing all needed facilitation to realising more CDM investments.

Practical implications

CDM as a policy has proved effective in eliminating gas flaring in the Nigerian oil and gas industry. The government should adopt this international policy to achieve more gas flaring reductions.

Social implications

Social problems of respiratory diseases, water pollution and food shortage among others due to gas flaring are persisting in oil and gas producing areas as government policies failed to end the problem. CDM projects in the industry have proved effective in eliminating the problem, thus improving the social welfare of the people and ensuring sustainable development.

Originality/value

The paper analysed the effectiveness of Nigerian Government policies and an international market-based mechanism towards ending gas flaring in its oil and gas industry.
