Purpose The purpose of this paper is to focus on the reference model of a grid-like supply network that enables formulation of delivery routing and scheduling problems in the context of the periodic vehicle routing problem. Design/methodology/approach The conditions for seamless (collision-free) synchronization of periodically executed local transport processes presented in this paper guarantee cyclic execution of supply processes, thereby preventing traffic flow congestion. Findings Systems that satisfy this characteristic, cyclic deliveries executed along supply chains are given and what is sought is the number of vehicles needed to operate the local transport processes in order to ensure delivery from and to specific loading/unloading points on given dates. Determination of sufficient conditions guaranteeing the existence of feasible solutions that satisfy these constraints makes it possible to solve the considered class of problems online. Practical implications The computer experiments reported in this paper show the possibilities of practical application of the proposed approach in the construction of decision support systems for food supply chain management. Originality/value The aim of the present work is to develop a methodology for the synthesis of regularly structured supply networks that would ensure fixed cyclic execution of local transport processes. The proposed methodology, which implements sufficient conditions for the synchronization of local cyclic processes, allows one to develop a method for rapid prototyping of supply processes that satisfies the time windows constraints given.

Harm facilitated by corporations has received increased attention in recent years. However, corporate crime and harm remain under-researched themes in relation to labour exploitation, in both theoretical and empirical terms. The purpose of this article is to argue that, in the context of agricultural and food supply networks, harmful labour practices result from structural problems associated with the demand for products. Although individual employers and businesses have a role in facilitating these harmful practices, these practices also emerge from otherwise legitimate agri-food supply network dynamics, such as subcontracted labour, which results in fragmented responsibility. Therefore, labour practices have significant implications for the nature, organization and control of corporate harms, whereby harmful consequences become normalized, accepted and embedded in agri-food supply network practices. Criminological analyses of food production and contemporary markets more widely can begin to address the systemic challenges of harmful labour practices, in both domestic and global supply networks.
