Chapter Leveraging Internet-of-Things to Support Circular Economy Paradigm in Manufacturing Industry

Circular economy represents a fundamental alternative to the currently predominating linear economy model, while Industry 4.0 is a technological enabler to bring process innovation in the industrial domain. New economic models are needed in order to reduce material inputs and waste generation leveraging on ecodesign, recycling and reusing of products, new business models, and new technologies. Internet-of-Things and artificial intelligence can support the circular economy paradigm, through the development of a marketplace for connecting buyers and sellers of manufacturing services, raw materials and products toward building global supply chains. The core component of this marketplace is a novel, agent-based, brokering module that will apply both syntactic and semantic matching in terms of manufacturing capabilities, in order to find the best possible supplier to fulfill a request for a service, raw materials or products involved in the supply chain

Process control and configuration of a reconfigurable production system using a multi-agent software system

Thesis (M. Tech. (Information Technology)) -- Central University of technology, Free State, 2011Traditional designs for component-handling platforms are rigidly linked to the product being produced. Control and monitoring methods for these platforms consist of various proprietary hardware controllers containing the control logic for the production process. Should the configuration of the component handling platform change, the controllers need to be taken offline and reprogrammed to take the changes into account. The current thinking in component-handling system design is the notion of re-configurability. Reconfigurability means that with minimum or no downtime the system can be adapted to produce another product type or overcome a device failure. The re-configurable component handling platform is built-up from groups of independent devices. These groups or cells are each responsible for some aspect of the overall production process. By moving or swopping different versions of these cells within the component-handling platform, re-configurability is achieved. Such a dynamic system requires a flexible communications platform and high-level software control architecture to accommodate the reconfigurable nature of the system. This work represents the design and testing of the core of a re-configurable production control software platform. Multiple software components work together to control and monitor a re-configurable component handling platform. The design and implementation of a production database, production ontology, communications architecture and the core multi-agent control application linking all these components together is presented

Intelligent Behavior of Autonomous Vehicles in Outdoor Environment

The objective of this PhD-project has been to develop and enhance the operational behaviour of autonomous or automated conventional machines under out-door conditions. This has included developing high-level planning measures for the maximisation of machine productivity as an important element in the continued efforts of planning and controlling resource inputs in both arable and high value crops farming. The methods developed generate the optimized coverage path for any field regardless of its complexity on 2D or 3D terrains without any human intervention and in a manner that minimizes operational time, skipped and overlapped areas, and fuel consumption. By applying the developed approaches, a reduction of more than 20% in consumed fossil fuel together with a corresponding reduction in the emissions of CO2 and other greenhouses is achievable.In this work, a software package for the autonomous navigation of field robotics over 2D and 3D field terrains and the optimization of field operations and machinery systems have been developed. A web-based version of the developed software package is currently under progress

Modelling water allocation in community irrigation using multi-agent system : A thesis submitted in partial fulfilment of the requirements for the Degree of Doctor of Philosophy at Lincoln University

Insufficient water for irrigation is a common problem in New Zealand, particularly in the Canterbury region, where the use and demand have been steadily increasing over the past 20 years (PCE, 2004; The Parliamentary Commissioner for the Environment, 2004). As a limited resource, there are restrictions around its use. While farmers who need water for irrigation can apply for consent through Environment Canterbury, the process takes a long time and is expensive. As a result, only those with large farms or those who will be able to realise greater financial benefits and higher levels of productivity tend to apply. Instead, most farmers apply to a community irrigation scheme such as Central Plain Water Limited (CPWL) who sells water to individual farmers. As a farmer must pay for each unit of water that s/he uses, s/he needs to have a good irrigation plan in place to ensure they obtain the maximum profit from their investment. In New Zealand, most farmers use computer programmes to estimate their irrigation requirements. The two most common programmes in New Zealand are IrriCalc and OVERSEER. However, both have some limitations: they can only be used to calculate the water needs of an individual farm and neither can prioritise crop water needs during periods of water scarcity. To deal with this problem, we designed an agent-based irrigation management system that can be used to optimise water allocation around the farm which is particularly useful during periods of water scarcity by taking into account the crop types and prioritising them based on the crop utility value. As it calculates the water savings based on each crop’s growth stage and prioritises it in terms of its potential sales price, this agent-based system provides a way to increase farmers’ profitability and to enables them to thrive during periods of water scarcity. During the water reduction exercise, most farms suffer from water shortages. However, there are farmers (who may have overestimated their water needs) who will have excess water. Recognising this situation, we developed a multi-agent system to improve water allocation within a community of water users (where each individual agent represents a farm) and investigated the efficiency of water distribution mechanisms among farms. Farmers can use the proposed multi-agent water management system to negotiate with each other to buy and sell water among themselves. One of the most well-known and simplest methods to achieve this is by using an auction. The choice of an auction was deliberate as it allows agents to buy water at a price, they are comfortable with. An agent must consider how much they are willing to pay for a specific volume of water to ensure their farm remains profitable. This study considered three-auction types and compared the results of each auction in terms of fair water distribution, profit for the sellers and reductions in losses for bidders. We found that the pay-per-bid auctions (discriminatory and uniform) are the best strategies for water distribution that balance between water distribution and gaining profit in water community. In addition, we also investigated how varying behaviours of sellers and buyer affect the outcome of the auction

Towards a simulation interoperability framework between an agent-based simulator and a BPMN engine using REST protocol

O paradigma atual de um modelo de processo de negócio é que é uma representação de uma sequência de tarefas que atuam sobre um “input” de dados, para produzir uma “output”, visando a produção de um novo serviço ou produto. Embora esta seja uma forma válida de interpretar um processo de negócio, ela não considera em pormenor a influência de fenómenos externos, por exemplo, comportamento humano, comunicação, interações sociais, a cultura organizacional que pode ter um efeito significativo na eficiência um processo de negócio. Como a dinâmica destes fenómenos externos não é linear, eles podem ser interpretados como um sistema complexo, que são sistemas que se comportam de tal forma que não podem ser explicados simplesmente olhando para o comportamento das suas partes individuais. Esta forma holística de pensar sobre os processos de negócio abre as portas à possibilidade de combinar diferentes métodos de simulação para modelar diferentes aspetos que influenciam um processo. A simulação baseada em agentes (ABS) e BPMN são escolhidas como os dois métodos de simulação para estudar o potencial dessa integração em processos de negócio, e a nossa abordagem para os combinar consiste em modelar o comportamento do utilizador em ABS e o próprio processo de negócio utilizando o BPMN. Por fim, a integração entre os dois motores de simulação acontece durante o decurso da simulação através da invocação de APIs usando o protocolo REST, onde os agentes controlam a dinâmica de execução do processo no BPMN. Esta abordagem de integração é validada através da construção de uma experiência, com o objetivo de determinar se os resultados de simulação obtidos são estatisticamente coerentesThe current paradigm of a business process model is that it is a representation of a sequence of tasks that act upon some data input, to produce an output, aiming the production of a new service or product to be delivered from a producer to a customer. Although this is a valid way of thinking, it neglects to consider in enough detail the influence of some phenomenon on inputs, e.g. human behaviour, communication, social interactions, the organisational culture which can have a significant effect on the output delivered by a business process. As the dynamics of these phenomena are non-linear, they can be interpreted as a complex system. This holistic way of thinking about business processes opens the doors to the possibility of combining different simulation methods to model different aspects that influence a process. A BPMN engine and an agent-based simulation (ABS) engine are chosen to serve the basis of our framework. In its conception, we not only consider the technical aspects of the framework but also delve into exploring its management and organizational dimensions, with the intent of facilitating its adoption in enterprises, as a tool to support decision support systems. We analyse how accurate the simulation results can be when using these two tools as well as what considerations need to be considered within organizations
