Uncertainty Aware Planning Scheduling Process

项目摘要

Process planning and scheduling problems are becoming increasingly complex due to the expanding production and customer base around the globe. A decision maker is continuously faced with the challenge to optimise the production plans and reduce costs under uncertainty. The uncertainty can be attributed to factors including volatile customer demands, variations in the process performance, fluctuations in socio-economics around the locations of the production plants, etc. Another complicating issue is the time-scale at which the decisions have to be taken and implemented. Not being able to effectively take these issues into account can lead to increased costs, customer dissatisfaction, loss of competitive edge and eventually shutting down of the manufacturing bases. This project aims to develop planning and scheduling tools for optimal decision-making under uncertainty while taking into account the multiple time-scales. Each process planning and scheduling problem is unique and hence one modelling and model solution tool cannot address the peculiarities of each problem. A framework where uncertainties are classified into specific categories is the key to providing cutting-edge optimal solutions. So, a problem will have a number of uncertainties which will be classified based upon our proposed framework and then for each classification the appropriate solution methodology will be invoked. A hybrid uncertainty modelling and optimisation tool that exploits the synergies of the solution techniques for various classes of uncertainty will also be developed. The novel planning and scheduling tools developed in this project will be tested on real-life case studies from process industries from a wide variety of sectors including energy systems, agrochemicals, pharmaceuticals, consumer goods, oil & gas, and industrial gases. Optimal planning and scheduling solutions based upon personalised uncertainty will be obtained.

由于全球的生产和客户群的扩大，过程计划和调度问题变得越来越复杂。决策者不断面临优化生产计划并降低不确定性成本的挑战。不确定性可以归因于包括波动客户需求，过程绩效的变化，生产工厂位置周围社会经济的波动等因素。另一个复杂的问题是必须做出决策和实施决策的时间表。无法有效考虑这些问题会导致成本增加，客户不满，竞争优势丧失以及最终关闭制造基地。该项目旨在开发计划和调度工具，以考虑到多个时间尺度，以在不确定性下进行最佳决策。每个流程计划和调度问题都是独特的，因此一个建模和模型解决方案工具无法解决每个问题的特殊性。将不确定性分为特定类别的框架是提供尖端最佳解决方案的关键。因此，问题将具有许多不确定性，这些不确定性将根据我们提出的框架进行分类，然后对于每个分类，将调用适当的解决方案方法。还将开发出利用解决方案技术协同作用为各种不确定性的混合不确定性建模和优化工具。该项目开发的新型规划和调度工具将对来自各种部门的流程行业的现实案例研究进行测试，包括能源系统，农业化学，药品，消费品，消费品，油气和工业气体。将获得基于个性化不确定性的最佳计划和调度解决方案。
