Management model for the logistics and competitiveness of SMEs in the city of Barranquilla

In Colombia, small and medium-sized enterprises (SMEs) are the most powerful engines of economic development, since they generate a high volume of jobs in the national territory, while diversifying productive, commercial, and service activities. In order to propose a model for logistics management as a component for the competitiveness of SMEs, a qualitative study is proposed that will allow us to collect from a structured review of recent literature, identifying the elements to be taken into account for logistics management in order to provide timely support and open space for continuous improvement. The proposed model is structured in six main blocks: characterization of processes according to the activity of the SME, external factors of influence, internal factors of influence, feeding of information, monitoring and control of operations, and feedback between support areas. The above elements have been analyzed and suggested taking into account the specific aspects of SMEs in the country, and taking into account the peculiarities of these small productive cells

Design of agile supply chains including analysing the trade-off between number of partners and reliability

The reliability of supply partners is particularly vital in agile supply chains as it is vulnerable to the inability of a supply partner to meet its high responsiveness and flexibility requirements resulting in the disruption of the whole network. Disruption can have expensive and extensive results for the entire agile supply chain. To mitigate the risk of disruption and improve the reliability of the whole agile supply chain, decision-makers need to pay more attention to supply chain design and construction, whilst simultaneously taking into account the sourcing strategy decisions. This paper proposes a series of models for the design of agile supply chains using dynamic programming modelling. These provide decision-makers with a systematic way of analysing one of the key decisions of sourcing strategy, namely the trade-off between the number of supply partners and reliability. The efficacy of the models is demonstrated through their application to a Chinese bus and coach manufacturer by way of an empirical illustration. The results show that this approach is effective for this application and it can be applied in other related decision-making scenarios. The methods offered in this paper provide managers with a practical tool to design their agile supply chains while considering the trade-offs between the number of partners and the reliability of the entire agile supply chain

The future of resilient supply chains

While supply chain resilience has been touched upon frequently, research remains (with the exception of often repeated anecdotal examples) relatively disparate on what disruptions actually are. This research aims to advance theoretical and managerial understandings around the management of supply chain disruptions. A two-stage research process is used which focuses first on polling academic experts. This stage is followed by the extraction of insights from practitioners in the automotive, electronics and food industries. Our findings coalesce around: (1) the types of disruptions that respondents are most concerned about; (2) the associated strategies suggested to cope with disruptions; and, (3) how resilience can be measured. It is apparent that there are some areas where academics and practitioners agree and others where they agree to a lesser extent. Both sets of actors tend to agree on how resilience can be quantified, with recovery time the preferred indicator. However, there is a discrepancy around how resilience is achieved within the supply chain. Academics emphasise the importance of redundancy while practitioners refer more to flexibility. Also, they disagree around what constitutes “key disruptions”: academics suggested high-profile events, while practitioners are more concerned with day-to-day problems

Sustainable supply chain management towards disruption and organizational ambidexterity:A data driven analysis

Balancing sustainability and disruption of supply chains requires organizational ambidexterity. Sustainable supply chains prioritize efficiency and economies of scale and may not have sufficient redundancy to withstand disruptive events. There is a developing body of literature that attempts to reconcile these two aspects. This study gives a data-driven literature review of sustainable supply chain management trends toward ambidexterity and disruption. The critical review reveals temporal trends and geographic distribution of literature. A hybrid of data-driven analysis approach based on content and bibliometric analyses, fuzzy Delphi method, entropy weight method, and fuzzy decision-making trial and evaluation laboratory is used on 273 keywords and 22 indicators obtained based on the experts’ evaluation. The most important indicators are identified as supply chain agility, supply chain coordination, supply chain finance, supply chain flexibility, supply chain resilience, and sustainability. The regions show different tendencies compared with others. Asia and Oceania, Latin America and the Caribbean, and Africa are the regions needs improvement, while Europe and North America show distinct apprehensions on supply chain network design. The main contribution of this review is the identification of the knowledge frontier, which then leads to a discussion of prospects for future studies and practical industry implementation

Call to Duty Just-in-Time Scheduling in a Restaurant Chain

Just-in-time scheduling has become ubiquitous in the service industries. While effective in reducing staffing level, hence labor cost, the potential impact of just-in-time scheduling on workers' productivity and the firm's revenue is not well understood. Using a dataset of 1,444,044 transactions from 25 stores of a full-service casual dining restaurant chain in the US, we study how just-in-time scheduling impacts worker productivity. We consider two types of just-in-time schedules: (1) short-notice schedules that are assigned to servers shortly prior to the day of service (mostly two days in our data), and (2) real-time schedules that are assigned to servers on the day of service. We show that short-notice schedules do not harm server productivity overall but real-time schedules do, by 4.4%. Our analysis indicates this may be because servers reduce their up-selling and cross-selling efforts when working on real-time schedules. We then propose an analytical scheduling model that accounts for both the value of staffing flexibility created through just-in-time scheduling and its impact on server productivity to inform the firm how to use just-in-time scheduling to improve profitability. Through a case study, we demonstrate that with the 4.4% productivity loss during the real-time schedules, the managers should shift from the heavy use of real-time scheduling toward scheduling more servers with longer advance notice. Such a shift not only provides more predictable work schedules for the workers, but can also improve restaurants' expected profit by up to 1%, a significant number for the low-margin restaurant industr

Approaches, challenges and impacts of Asian regional multimodal logistics for supply chain integration and interdependencies

Asia’s successful economic growth over the past few decades is well known and is receiving increasing attention from current and potential trading partners. The region is home to some of the world’s largest emerging and dynamic economies, and this includes the 10 countries of the Association of Southeast Asian Nations (ASEAN). Along with this growth, there is a recognition that trade costs, along domestic and international supply chains in these Asian economies, can be significantly reduced by improving the logistics performance in each mode of transport involved in various logistics and supply chain transactions. These improvements may be conveniently facilitated by the optimisation of the transitioning strategies from unimodal to multimodal (or combined) transport services. In this context, we examine here the status of current multimodal logistics in the provision of supply chain integration and interdependencies practiced in the key Asian economies. For this chapter we have particularly focused on the current approaches, challenges and potential impacts of transforming and enhancing the levels of logistics and supply chain multimodal integration and interdependencies on the emerging economies of this region
