“…Namely, some authors have solved these instances without considering the time limit on the routes (Nagy & Salhi, 2005;Dethloff, 2001;Crispim & Brandão, 2005;Chen & Wu, 2006;Montané & Galvão, 2006), while other have solved them with the time limit in place (Nagy & Salhi, 2005;Dethloff, 2001;Montané & Galvão, 2006;Wassan et al, 2008). Furthermore, some authors include the service time (Nagy & Salhi, 2005;Dethloff, 2001) and some do not (Montané & Galvão, 2006;Wassan et al, 2008). To complicate matters even more, Nagy and Salhi (2005) allow for two visits to each customer, one for delivery and one for pickup.…”

“…To complicate matters even more, Nagy and Salhi (2005) allow for two visits to each customer, one for delivery and one for pickup. Therefore, for this data set, we limit our comparison to the results of Montané and Galvão (2006) and Wassan et al (2008), both of which use a time limit on the routes, no service time and a single visit to each customer (i.e., simultaneous delivery and pickup).…”

Wassan et al (2008) apply reactive tabu search, while Zachariadis et al (2009) suggest a hybrid tabu search and guided local search procedure.

Though its origins can be traced back to 1977, the development and application of the metaheuristic Scatter Search (SS) has stayed dormant for 20 years. However, in the last 10 years, research interest has positioned SS as one of the recognizable methodologies within the umbrella of evolutionary search. This paper presents an application of SS to the problem of routing vehicles that are required both to deliver and pickup goods (VRPSDP). This specialized version of the vehicle routing problem is particularly relevant to organizations that are concerned with sustainable and environmentally-friendly business practices. In this work, the efficiency of SS is evaluated when applied to this problem. Computational results of the application to instances in the literature are presented.

“…The local organization responsible for promoting SRI in the three study villages, the Mount Valley Development Agency (MVDA), based its information about RBNs from the People's Science Institute (PSI), the coordinating NGO for SRI in Uttarakhand. PSI itself followed the guidelines of WASSAN (WASSAN, 2006), Secunderabad for practicing SRI. It advocated the use of RBNs for SRI, in particular fertilising the seedbed and using low seeding density.…”

How Smallholder Farmers in Uttarakhand Reworked the System of Rice Intensification: Innovations from Sociotechnical Interactions in Fields and Villages

How Smallholder Farmers in Uttarakhand Reworked the System of Rice Intensification: Innovations from Sociotechnical Interactions in Fields and VillagesThe System of Rice Intensification (SRI) is presented in Asia and other parts of the world as an alternative 'agro-ecological' and 'farm-based' innovation in rice production. SRI calls for modifications in crop-management practices without relying on external inputs, which makes it different from innovations based on new rice varieties, which became dominant since the Green Revolution. SRI practices are therefore said to be appropriate for resource-poor smallholder farmers.Previous studies on SRI have focused mainly on the yield effects in comparison with other crop management practices, overall costs and benefits of SRI or deviations from recommended practices. These studies have largely neglected farmers' underlying strategies. This thesis provides an understanding of whether and how SRI can be called a 'farm-based' innovation. Rather than returning to earlier debates about SRI's adoption and disadoption, the study looks as how farm households and communities in Western Himalayan region of India responded to the introduction of SRI.The main objective of this research was to understand how farmers respond to an intervention like SRI and what this tells us about SRI as a socio-technical system. The main research question addressed by this thesis is how SRI, conceived as a set of practices introduced from outside the communities, was incorporated into the local rice farming system. Specifically, the thesis examines how existing work groups were adjusted to accommodate the new method, how the SRI practices were interpreted and adjusted to fit with the local social and agro-ecological arrangements, and how the new method influenced existing rice farming practices in the locality.The research was carried out in three contrasting villages of Uttarakhand, located in the Bhilangana sub-basin of the Western Himalayan region of India. SRI was introduced in this area in 2008. Fieldwork in the three villages was conducted throughout two rice seasons.The theoretical resources drawn upon for this research include the concept of "sociotechnical system", "agriculture as performance", and the culture of "task groups". Together these concepts help to understand rice farming as a collective and mutually shaping social and technical performance rather than the activity of an individual farmer. The thesis shows how existing and new rice farming practices and task groups are reconfigured through socio-technical innovations within a given agroecological setting. SRI acted as a catalyst, initiating a process of readjustments in the socio-technical configurations of rice farming, varying according to the local context. Farm households, while incorporating SRI into the existing farming system, try to ii seek complementarity and synergy between various rice farming methods. This allows fluidity among task groups and leads to the extension and diversification of the repertoire of m...
