Advances in Production Management Systems: Innovative and Knowledge-Based Production Management in a Global-Local World
The three volumes IFIP AICT 438, 439, and 440 constitute the refereed proceedings of the International IFIP WG 5.7 Conference on Advances in Production Management Systems, APMS 2014, held in Ajaccio, France, in September 2014. The 233 revised full papers were carefully reviewed and selected from 271 submissions. They are organized in 6 parts: knowledge discovery and sharing; knowledge-based planning and scheduling; knowledge-based sustainability; knowledge-based services; knowledge-based performance improvement, and case studies.
Optimum Cereal Combine Harvester Operation by Means of Automatic Machine and Threshing Speed Control
The method by which automation of agricultural machinery can be developed is illustrated in the case of cereal combine harvesting. The controlled variables are machine forward speed and threshing cylinder peripheral speed. Four control systems have been developed that optimise these speeds on the basis of harvest costs minimisation, which includes variable and fixed costs of the machine and those of machine- and timeliness losses. The evaluated systems make use of a varying number of input process variables and control the machine speed exclusively, or both machine speed and threshing speed. The financial benefits from these control systems were calculated by means of a computer simulation. The research required in developing the models and control systems is discussed in detail. The simulation results demonstrate that control of low-frequency variations in crop properties brings some slight benefit and indicate that timeliness losses are of great importance to optimisation..
Technology Meets Flowers
Why do the Dutch continue to play a central role in the global production, sales, and distribution of flowers? What are the origin and history of the bulb and flower industry in the Netherlands? How are Artificial Intelligence (AI), complex algorithms, and modern distribution systems ensuring that fresh flowers reach their destination on time? This very entertaining and informative book introduces readers to the global flower business, and highlights the surprising factors that helped the Dutch become global leaders on the flower markets. The book reveals the complexity of the flower markets in terms of their ability to produce, transport, and deliver fresh flowers on a global scale. In addi...
Greenhouse Horticulture
This book provides an integrated approach to crop growth and development and the technical aspects of greenhouse cultivation and climate management. It combines an analysis of the relationship between crop production and ambient climate with an explanation of the processes that determine the climate in a protected environment. With the ability to modify the environment comes the need for growers to strike a balance between the costs and benefits of technology. This book outlines the methods and gives several examples of how to make 'optimal' choices about technology. Sustainable management of shoot and root environment is discussed, as well as the pros and cons of vertical farming. The processes addressed in this book, like crop growth, energy balance and mass exchange, apply to any kind of greenhouse. Therefore, in spite of the word 'technology', this is not a book about high-tech greenhouses only. 'Greenhouse horticulture' is an easy-to-read textbook for all those interested in protected cultivation, from university students and teachers to professional advisers in the field and managers of horticultural companies.
