    This paper presents an alternative to the location of distribution centres considering a multi-objective model minimising insecurity cost and road access for a case study in the City of Barranquilla (Colombia). For the solution of the model, 15 different scenarios of variation of the importance of the proposed objectives are considered. As a basis for the design of the modelling, the characterisation and classification of the variables with the highest incidence in the location of distribution centres or warehouses are posed. It is possible to demonstrate the impact of the evaluation and analysis of the mathematical model for the location of this type of facility

    A FUZZY GOAL PROGRAMMING APPROACH FOR SOLVING MULTI-OBJECTIVE SUPPLY CHAIN NETWORK PROBLEMS WITH PARETO-DISTRIBUTED RANDOM VARIABLES

    Uncertainty is unavoidable and addressing the same is inevitable. That everything is available at our doorstep is due to a well-managed modern global supply chain, which takes place despite its efficiency and effectiveness being threatened by various sources of uncertainty originating from the demand side, supply side, manufacturing process, and planning and control systems. This paper addresses the demand- and supply-rooted uncertainty. In order to cope with uncertainty within the constrained multi-objective supply chain network, this paper develops a fuzzy goal programming methodology, with solution procedures. The probabilistic fuzzy goal multi-objective supply chain network (PFG-MOSCN) problem is thus formulated and then solved by three different approaches, namely, simple additive goal programming approach, weighted goal programming approach, and pre-emptive goal programming approach, to obtain the optimal solution. The proposed work links fuzziness in transportation cost and delivery time with randomness in demand and supply parameters. The results may prove to be important for operational managers in manufacturing units, interested in optimizing transportation costs and delivery time, and implicitly, in optimizing profits. A numerical example is provided to illustrate the proposed model

    Advancing Consumer Behavior: The Role of Artificial Intelligence Technologies and Knowledge Sharing

    Get PDF
    The increasing use of digital technologies has significantly reshaped marketing and consumer behavior (CB) as online communities and cutting-edge innovations such as artificial intelligence (AI) disrupt and advance consumer attitudes on specific products and services. As such, online communities that are supported by AI technologies creating new knowledge from consumer interactions through platforms like social media as consumers share experiences on specific products or services. Since AI is designed to “learn” and improve with data generated from digital technologies linked to consumer interactions, AI relies on consumer knowledge-sharing (KS) activities to replicate new knowledge for product and service improvement. However, given the knowledge gap in this area, this article applies the fsQCA technique to data generated from 291 participants to develop CB metaframework predicted on the concepts of AI, CB, and KS. Our results suggest that AI advances consumer attitudes and behaviors when knowledge is acquired while online communities promote curiosity and engage consumers to learn by sharing experiences about specific products or services. Furthermore, understanding the causality between AI, CB, and KS concepts offers critical decision-making insights to marketing experts across the industry

    A hybrid multi-objective approach to capacitated facility location with flexible store allocation for green logistics modeling

    Get PDF
    We propose an efficient evolutionary multi-objective optimization approach to the capacitated facility location–allocation problem (CFLP) for solving large instances that considers flexibility at the allocation level, where financial costs and CO2 emissions are considered simultaneously. Our approach utilizes suitably adapted Lagrangian Relaxation models for dealing with costs and CO2 emissions at the allocation level, within a multi-objective evolutionary framework at the location level. Thus our method assesses the robustness of each location solution with respect to our two objectives for customer allocation. We extend our exploration of selected solutions by considering a range of trade-offs for customer allocation

    Network Flexibility for Recourse Considerations in Bi-Criteria Facility Location

    What is the best set of facility location decisions for the establishment of a logistics network when it is uncertain how a company’s distribution strategy will evolve? What is the best configuration of a distribution network that will most likely have to be altered in the future? Today’s business environment is turbulent, and operating conditions for firms can take a turn for the worse at any moment. This fact can and often does influence companies to occasionally expand or contract their distribution networks. For most companies operating in this chaotic business environment, there is a continuous struggle between staying cost efficient and supplying adequate service. Establishing a distribution network which is flexible or easily adaptable is the key to survival under these conditions. This research begins to address the problem of locating facilities in a logistics network in the face of an evolving strategic focus through the implicit consideration of the uncertainty of parameters. The trade-off of cost and customer service is thoroughly examined in a series of multi-criteria location problems. Modeling techniques for incorporating service restrictions for facility location in strategic network design are investigated. A flexibility metric is derived for the purposes of quantifying the similarity of a set of non-dominated solutions in strategic network design. Finally, a multi-objective greedy random adaptive search (MOG) metaheuristic is applied to solve a series of bi-criteria, multi-level facility location problems

    An integrated framework for improving supply chain performance

    In 2009, Roland Berger Strategy Consultants [Roland Berger Strategy Consultants, (2009). Global SCM excellence study., p.5.] reported that 40% of 234 companies had the wrong priorities in regard to efficiency vs. responsiveness. In 2014, PricewaterhouseCoopers (PwC) and American Production and Inventory Control Society (APICS) [PwC and APICS, Sustainable supply chains: Making value the priority 2014] found that 76% of 500 supply chain executives identified sustainability as an important aspect of their supply chain. The results highlight the importance of achieving consistency between customer expectations, in terms of cost and service level, and supply chain performance in today’s competitive business environment. Despite this, however, no integrated supply chain design framework exists to control majority of the important functions related to supply chain strategy, structure, process and performance. The literature review showed that simulation is rarely considered at the strategic level, but the research experiments highlighted a number of ways in which simulation tools might be useful at this level, such as exploring the impact of strategic fit and decoupling points, and assessing different supply chain network configurations and policies. This research contributes to knowledge by designing and developing a framework that integrates strategy, process and resources, and allows the use of simulation tools to consider the three dimensions of efficiency, responsiveness and sustainability concurrently during the design process. The proposed framework is validated using a hypothetical supply chain network. Simulation allows performance to be assessed under a range of scenarios. The simulation experiments showed that under the suggested policies, efficiency improved from 25.38% to 30.58% and responsiveness rose from 18.37% to 32.78%. However, they also indicated that while policies oriented towards improving responsiveness had a positive impact on sustainability, those oriented towards improving efficiency had a negative impact. The significance of the research lies in its development of a supply chain design framework that could assist companies in achieving the optimum configuration of supply chain resources, thereby helping them reduce inventory, lower costs, enhance responsiveness and improve strategic focus in terms of design, execution and capital investments
