Improving social welfare chain using optimal planning model

Abstract

Purpose -The purpose of this study is to introduce the concept of social welfare chain and address the challenges in decision making through the development of an optimal planning model for a nongovernmental organization (NGO). The distinctive properties of the social welfare chain and its relationship with the humanitarian relief chain in the context of supply chain management are also discussed. The paper presents a real decision problem and analyzes the managerial impacts of the proposed solution. Design/methodology/approach -The study of social welfare policy and the review of the humanitarian literature has necessitated the introduction of the social welfare chain. Based on its definition, an optimal facility location distribution model that consolidates the non-integrated style of logistics functions with a cost minimizing approach is developed. The General Algebraic Modeling System (GAMS) is used in order to optimize the coal distribution model of an NGO. Data is obtained from an NGO that aims to help vulnerable people through distributing coal and basic food such as rice and sugar. Findings -Besides laying the foundations of social welfare chain, an analytical tool for decision support systems of the NGOs can be considered as the major finding of the research. Despite the increased number of stages in the proposed network configuration, the optimal solution resulted in significant cost reduction and distribution efficiency due to the availability of temporary distribution center locations at no extra cost. Furthermore, this study brings out the advantages of using intermodal transportation in the distribution process of cost-sensitive networks. Practical implications -This paper provides a detailed analysis that contributes to the efficiency and the effectiveness of social welfare chains. Moreover, it represents a cooperation established between university and NGOs. Originality/value -The planning efforts of nongovernmental organizations targeting at the periodical aids to improve the social welfare level have received little attention in the literature. This paper is the first to propose the concept of "Social Welfare Chain", at the same time addressing the distribution planning for the NGO.

Cross-sector humanitarian–business partnerships in managing humanitarian logistics: an empirical verification

“…FAO works with commercial companies to help small farmers and beneficiaries increase their production and link them to markets. For the beneficiaries, the partnerships help to deliver better development programmes (Adivar et al 2010;Manning and Roessler 2013). For non-governmental sector actors, a partnership with the private sector can help addressing resource-and budgetary issues (Dinesh, Lisa, and Eric 2014).…”

Modeling for the equitable and effective distribution of donated food under capacity constraints

“…Second, in our case the donated supply is much less than the total demand, so satisfying demand is not a useful objective. Adivar et al (2010) point out that operations research has been widely used for sudden-onset disaster relief operations but -very little, if any, research focuses on optimizing relief efforts for slow-onset disasters or social welfare operations.‖ These authors work with an NGO in Turkey to optimize coal distribution by choosing optimal transfer sites and the corresponding shipment amounts using a mixed integer linear program to minimize total cost under various constraints. Celik et al (2012) study a strategic decision problem based on planning the expansion of a supply chain for banking donated human breast milk in South Africa in order to ensure that every needy infant has equal probability of access to donated breast milk.…”

Evaluation of a facility location for a food assistance supply chain. The case of Bienestarina in Colombia

“…The warehouse location requirement is coherent with previous studies in the literature. For instance, in business logistics research, the mathematical models fare common or allocating or selecting warehouses from a set of alternatives (Adivar et al, 2011;Owen and Daskin, 1998). In a humanitarian logistics context, the problem is similar, but the facilities activated are pre-positioned facilities for relief storage and response instead of warehouses (Balcik and Beamon, 2008;Li et al, 2014;Trivedi and Singh, 2018;Singh, 2016;Ukkusuri and Yushimito, 2005).…”
