The current economic crisis is reflected in lower capacity expansion or even capacity contraction, closing of distant activities and reduction of lead time. However, the locations of suppliers are strongly connected with the quality of agricultural products. The transportation from distant locations can largely affect the food production business in all aspects. The article presents how the Extended Material Requirements Planning (EMRP) model enables to evaluate perturbations in lead time and temperature, and shows how distant growing areas of agricultural products, and, as a result, transportation lead times play a crucial role in the net present value calculation. In this paper, we show the impact of choosing a less distant site for growing of agricultural products, and overlapping the transportation and quarantine lead times on decreasing the perishability, hence increasing the added value in multi-level food assembly systems. Also, a case study of Spanish baby food industry is presented, using the principles of the well-developed EMRP Theory.

Sustainable Urban Mobility Plans (SUMP) are increasingly popular planning tools in cities with environmental issues where numerous actions are usually proposed to reduce pollution from urban transport. However, the diagnosis and implementation of these processes requires broad consensus from all stakeholders and the ability to fit them into urban planning in such a way that it allows the proposals to become realistic actions. In this study, a review of the sustainable urban mobility plans of 47 cities in Spain during the last 15 years has been carried out, analyzing both the diagnosis and proposal of solutions and their subsequent implementation. From the results obtained, a new framework based on a structured hybrid methodology is proposed to aid decision-making for the evaluation of alternatives in the implementation of proposals in SUMP. This hybrid methodology considers experts’ and stakeholders’ opinion and applies two different multi-criteria decision making (MCDM) methods in different phases to present two rankings of best alternatives. From that experience, an analysis based on the MCDM methods called ‘Sequential Interactive Modelling for Urban Systems (SIMUS)’ and weighted sum method (WSM) was applied to a case study of the city of Cartagena, a southeastern middle-size city in Spain. This analytic proposal has been transferred to the practical field in the SUMP of Cartagena, the first instrument of this nature developed after COVID-19 in Spain for a relevant city. The results show how this framework, based on a hybrid methodology, allows the development of complex decision mapping processes using these instruments without obviating the need to generate planning tools that can be transferred from the theoretical framework of urban reality.
