Purpose
– The purpose of this paper is to analyze the best way to implement sustainable practices in the Logistics Social Responsibility field. Using the best practices (BPs) approach, the authors have answered the question about how logistics function can take on board the principles of sustainability.
Design/methodology/approach
– A systematic literature review has been applied, with an analysis of 194 papers from relevant logistics/supply chain management (SCM)-related journals over a 20-year time frame.
Findings
– The authors have identified a first set of traditional BPs that are still relevant in the sustainability context, a second set of innovative sustainable BPs and a third set that can be considered sustainable BPs evolved from the traditional cost-efficiency approach, serving as a link between the other ones. This proposed taxonomy of BPs charts a progressive path toward integration of sustainable principles in SC-logistics operations.
Research limitations/implications
– The methodological approaches applied entail inherent limitations. However, the authors have set out to ensure rigor by following a structured process approach.
Originality/value
– The work contributes by filling two recurring gaps identified in the literature: the need to integrate social and environmental issues and develop more practical tools for implementing sustainable SCM. The progressive way of implementing sustainable BPs has advantages for logistics managers, especially when companies have limited resources for transforming their logistics process into a sustainable process. Additionally, future academic research topics are proposed.
Most of the mobile robot control frameworks are based on a middleware layer with several independent modules that implement primitive actions and report events about their state. These modules are usually connected with different interprocess communication mechanisms. Here, we propose to use hierarchical interpreted binary Petri nets to coordinate the activity of these modules. Tasks are described using an interpreted Petri net editor and saved in a xml file. A dispatcher loads these files and executes the different Petri nets under user requests. A monitor that shows the state of all the running nets is very useful for debugging and tracing purposes. The whole system has been applied to a guide robot (vixiabot) that has been guiding users in a public event (XuventudeGalicia.net) for three days in April 2007 and is now extended to a multirobot surveillance application.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
