title: Designing and planning a rice supply chain: a case study for Iran farmlands
abstract: aPh.D. candidate, School of Industrial Engineering, Iran University of Science and Technology, Iran bAssociate Professor, School of Industrial Engineering, Iran University of Science and Technology, Iran C H R O N I C L E A B S T R A C T Article history: Received December 10, 2019 Received in revised format: December 28, 2019 Accepted  2020 Agricultural food supply chains of different grains such as wheat, rice, and corn include several processes from cropping and harvesting to distribution. Integrating these processes to reduce costs, in addition to providing sufficient supply, are of the major goals of agri food supply chain management. Rice is an important grain that constitutes an important part of people's diets throughout the world. FAO predicts that global rice utilization would increase over the next few years. Considering rice's importance, in this paper, a mixed integer linear mathematical model for designing and planning of rice supply chain is proposed which aims to maximize total profit by integrating different decisions of the rice supply chain including supplier selection, cropping, fertilizing, pest control, harvesting, milling, transportation, and distribution. This model considers different rice varieties and takes into account irrigation water requirements of crops and available water resources. A case study of Iran farmlands in Gilan province is employed to show the applicability and advantages of the proposed model for the rice supply chain. Results indicate that increasing conversion ratio of paddy to rice and reducing labor costs would have a significant impact on the total profit of the supply chain.

title: Designing and solving a bi level model for rice supply chain using the evolutionary algorithms
abstract: According to the recent gigantic development in the agricultural section, Agricultural Supply Chain (ASC) management has attracted both researchers and agronomic practitioners. In this regard, rice as one of the important agricultural products is generally cultivated by rural farmers in small farmlands. Due to the high demand, high price, type of products, and also wide geographic range of production and consumption, the rice supply chain has special characteristics in ASC. In this regard, this paper not only firstly considers rice supply chain and but also proposes a bi level optimization model for rice supply chain. The proposed model aims to minimize total cost with respect to the two decision makers' opinions. Since, the bi level programming is NP hard, to solve the proposed model, two well known meta heuristic algorithms including Genetic Algorithm (GA) and Particle Swarm Optimization (PSO) along with two hybrid algorithms (PSO GA and GA PSO) and a modified algorithm (GPA) are utilized. In order to fill the literature gaps and to get closer to real world applications, an applicable example in Iran is studied. Based on the results and managerial insights, the GPA is chosen as the best method and its allocated value of the variable are reported. The results show that the proposed model and solution methods are valid, practical, and effective. Also, in order to provide an insight to the functionality of the model and the results of the case, some sensitivity analyses on the major model parameters such as the demand are provided.

title: Community Development through Supply Chain Responsibility: A Case Study of Rice Supply Chains and Connected Rural Communities in Central China
abstract: Supply chains depend on community resources such as entrepreneurs, natural resources, and facilities in value creation and successful operation, while communities need development opportunities from supply chains to build and maintain prosperity. The mutual influence between supply chains and communities offers opportunities to integrate sustainability initiatives into the chain. The concept of supply chain responsibility (SCR) represents a new philosophy that helps create value for communities, but so far does not link well with the idea of community and is viewed one chain at a time. A more integrated and holistic consideration of supply chain community interactions incorporating multiple supply chains and communities adds to the perspective of community development through SCR. It not only leverages community development as a significant level of analysis in supply chains, but also considers all chains that interact with a community. We use a case study in China's rice industry to examine the complex and multifaceted supply chain community interactions in a network of three types of rice supply chain and two rural communities, to understand the theoretical and practical potential in an enriched conceptualization of SCR. The interactions among the supply chains and communities provide significant insights into how to create sustainability for both.

title: Contract Farming in the Mekong Delta's Rice Supply Chain: Insights from an Agent Based Modeling Study
abstract: In this paper, we use agent based modeling (ABM) to study different obstacles to the expansion of contract rice farming in the context of Mekong Delta (MKD)'s rice supply chain. ABM is a bottom up approach for modeling the dynamics of interactions among individuals and complex combinations of various factors (e.g. economic, social or environmental) Our agent based contract farming model focuses on two critical components of contractual relationship, namely financial incentives and trust. We incorporate the actual recurrent fluctuations of spot market prices, which induce both contractor and farmer agents to renege on the agreement. The agent based model is then used to predict emergent system wide behaviors and compare counterfactual scenarios of different policies and initiatives on maintaining the contract rice farming scheme. Simulation results firstly show that a fully equipped contractor who opportunistically exploits a relatively small proportion (less than 10% of the contracted farmers in most instances can outperform spot market based contractors in terms of average profit achieved for each crop. Secondly, a committed contractor who offers lower purchasing prices than the most typical rate can obtain better earnings per ton of rice as well as higher profit per crop. However, those contractors in both cases could not enlarge their contract farming scheme, since either farmers' trust toward them decreases gradually or their offers are unable to compete with the benefits from a competitor or the spot market. Thirdly, the results are also in agreement with the existing literature that the contract farming scheme is not a cost effective method for buyers with limited rice processing capacity, which is a common situation among the contractors in the MKD region. These results yield significant insights into the difficulty in expanding the agricultural contracting program in the MKD's rice supply chain.

title: The impact of environmental uncertainty on the performance of the rice supply chain in the Ayeyarwaddy Region, Myanmar
abstract: In this paper, we study the relationship between environmental uncertainty and performance in the rice supply chain in the Ayeyarwaddy Region, Myanmar. Efficiency is one of the important performance indicators in both supply chain and agribusiness. In this regard, the objectives of the study are to identify the different sources of uncertainty perceived by the different actors in the supply chain, to measure the rice supply chain efficiency, and to study the impact of the environmental uncertainty on the supply chain efficiency. The data of 215 respondents is collected from the Ayeyarwaddy Region by using a purposive and stratified random sampling method, and we analyze this data via descriptive statistics, an exploratory factor analysis, data envelopment analysis (DEA) and Tobit regression analysis. The scores for the technical, pure, and scale efficiency show a very low performance of the rice supply chain in the Ayeyarwaddy Region resulting from the fact that most of the rice businesses are too small and need to expand their operating size. We found that this global rice supply chain performance is significantly impacted by the planning and control uncertainty and the climate uncertainty. Therefore, mitigation initiatives must be developed such as financial insurance mechanisms and extension services should be widespread. Both aim to improve the impact of the climate adverse conditions and to increase the efficiency of resource utilization in the supply chain. Moreover, the actors should organize themselves in cooperatives such that the scale of operations can be increased and information is captured and shared between different parties in the supply chain. This is crucial to operational control and planning because a higher quality of information input will increase the quality of managerial decision making.

title: A Blockchain Technology Solution to Enhance Operational Efficiency of Rice Supply Chain for Food Corporation of India
abstract: Rice and wheat are the staple food grains among the major commodities that are procured and securely stored by Food Corporation of India (FCI) which is the responsible body to implement the decisions made by the Ministry of Consumer Affairs, Food and Public Distribution (MCAFPD) The Government of India (GOI) alongside other state offices, attempts procurement of wheat and rice under price support scheme. Food grains are procured from farmers from mandis, and then they are moved to various FCI depots through rail or road and finally distributed to state agencies for public distribution. FCI has been able to make sure the availability of sufficient foodgrains in depots of all states by proper planning and efficient supply chain operations. For effective SCM, FCI has implemented IIFSM (Integrated information system for food grain management) and FAP (Financial accounting package) to make the increasing demand of the population and food security. We have studied the existing FCI's supply chain management for rice, and the extensive literature review was also done to understand the supply chain management in the food sector. To escalate and track the productivity of paddy and increase the security and efficiency of rice supply chain operations of FCI, we have proposed a Blockchain technology model of RSCM (Rice Supply Chain Management) in this paper.

title: Analysis of Distribution Information System of Rice Supply Chain Management at PT. Jatisari Sri Rejeki
abstract: One of Indonesia's commodities that has great potential is rice. Rice is a strategic commodity and is a staple food of the Indonesian nation. The consumption of rice every year always increases along with the rate of population increase while the increase of rice consumption is not comparable with the rate of increase of production and harvest area. The sequence of rice processes undergoes several stages of the supply chain: agriculture (growing) harvesting, harvesting, packing, and transportation. In terms of actors, the supply chain consists of several businesses such as farmers, local wholesalers such as collecting traders, traditional retailers supermarkets, and customers. PT. Jatisari Sri Rejeki Karawang is one of the companies that organize the management of food industry business especially the rice along with its chain of activities in an integrated manner by utilizing all resources effectively, efficiently and synergistically so as to increase business growth to achieve the intent and purpose of the company.
