Operative planning in agricultural production has historically had the objective of improving yields and quality. Sowing, cropping, and harvesting are usually treated independently, and waste and the sustainability of operations are generally not integrated into operational planning methodologies for agricultural production. This study shows the need to have a clear and precise methodology to minimize waste in agricultural production systems to ensure sustainability. This need is addressed with a novel methodological guide to minimizing waste in agricultural operations, crop maintenance, and harvesting. The proposed methodology is founded on the use of lean manufacturing as a waste-management tool. Lean manufacturing principles allow agricultural operations and the variables that represent wastes to be identified, mathematical models to be built, constraints to be defined, and the cost of waste to be illustrated, as well as its minimization through an objective function. To guide implementation, we propose a conceptual model to explain the construction of a mathematical model that represents the development of decision variables on agricultural operations with the elements to consider and the constraints and theoretical proposal of the necessary objective function. The proposed conceptual model and the constructed methodology constitute a novel development within agricultural production systems that could be used by decision makers and farmers. © 2019 Society of Chemical Industry.
农业生产中的作业规划历来旨在提高产量和质量。播种、种植和收获通常是独立进行的，而且作业的浪费和可持续性通常未被纳入农业生产的作业规划方法中。本研究表明，需要有一种明确而精确的方法来最大限度地减少农业生产系统中的浪费，以确保可持续性。为了满足这一需求，我们提出了一种新颖的方法来最小化农业作业、作物维护和收获中的浪费。所提出的方法基于使用精益制造作为浪费管理工具。精益制造原则允许确定农业作业和代表浪费的变量，构建数学模型，定义约束，并说明浪费的成本及其通过目标函数最小化。为了指导实施，我们提出了一个概念模型来解释构建一个数学模型，该模型代表了在农业作业中考虑的元素和必要的目标函数的约束和理论建议下开发决策变量。所提出的概念模型和构建的方法构成了农业生产系统中的一个新发展，决策者和农民可以使用。 © 2019 化学工业学会。
