Ec89-723 Irrigation Scheduling Using Soil Moisture Blocks In Silty Soils, William L. Kranz, Dean E. Eisenhauer

University of Nebraska-Lincoln Extension: Historical Materials

Irrigation takes some risk out of crop production by providing a reliable source of water that allows the producer to manage soil water. Monitoring soil water is fundamental to determining how much irrigation water should be applied, and when the soil is able to store the amount of water to be applied.

This publication describes how to use soil mositure blocks to schedule irrigations in fine textured soils.

Application Of Distributed Knowledge Bases In Intelligent Manufacturing, Cihan H. Dagli, Gerald E. Hoffman

Engineering Management and Systems Engineering Faculty Research & Creative Works

The authors consider independent knowledge bases operating on separate work stations networked together within the domain of knowledge-based scheduling. The scheduling problem is addressed through distributed knowledge bases that have an ability to pass information back and forth between small knowledge bases functioning at different decision-making levels. A small manufacturing plant is conceptualized in order to experiment with this process. The general outline and areas of the manufacturing shop are shown. The domain specific area for the knowledge bases is to optimize the scheduling of work at each work station in order to meet a weekly quota. Automatic guided vehicle, …

Proposed Scheduling Methods For Printed Circuit Board Assembly, Tali Freed, Ezey M. Dar-El, Oded Z. Maimon

Industrial and Manufacturing Engineering

The current practice in the assembly of electronic components on printed circuit boards (PCB's) is serial production, a process characterized by very long set-up times.

However. with the advent of efficient on-line process information, new production control methods are now possible. This paper proposes two new production methods - the Grouped Set-up (GSU) method and the Sequence-Dependent Scheduling (SDS) method, which can significantly reduce set-up times.

It is shown that the GSU always performs better than the SDS method in terms of total production flow (throughput). while the SDS performs better than the GSU method in terms of work-in-process (WIP) …

Two-Step Optimal Thermal Generation Scheduling, B Fardanesh, F. Eugenio Villaseca

Electrical and Computer Engineering Faculty Publications

A new approach to the solution of the optimal thermal generation scheduling problem is presented. The problem is solved in two steps. As a first step, the optimal production schedule for the next day is obtained based on a daily load forecast, reserve capacity requirements, and present status of generating units. The second-step algorithm uses the results of the first step and adjusts the previous schedule to meet new constraints developed during the course of the day. Variable truncation dynamic programming is proposed as a new method to reduce computation effort. To eliminate the need for solving the …

Optimal Allocation And Scheduling Of Irrigation Water For Cotton And Soybeans, M. J. Cochran, L. D. Parsch, J. M. Redfern, H. D. Scott

Technical Reports

This study evaluated alternative irrigation scheduling strategies for cotton and soybean production on Sharkey clay soils in southeast Arkansas. Strategies were ranked on the basis of two basic criteria: expected net revenue and risk efficiency. Risk efficiency was defined for different risk preferences using stochastic dominance techniques. Preferred strategies for cotton employed tensiometer thresholds between -.45 atm and -.75 atm. Risk efficient soybean irrigation strategies varied with the degree of risk aversion--more risk averse decision makers prefer strategies with lower thresholds.

G85-753 Irrigation Scheduling Using Crop Water Use Data, C. Dean Yonts, Norman L. Klocke

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide describes using the "checkbook" method to schedule irrigations based on crop water use data.

Irrigation scheduling determines when and how much water to apply to meet crop demand. Soil water status and current crop water use are key factors for scheduling irrigations. Field observations and crop growth stage are important, but scheduled irrigations result in better rainfall use while avoiding crop water stress or excessive irrigation.

G77-340 Scheduling Irrigation By Electrical Resistance Blocks, Paul E. Fischbach

University of Nebraska-Lincoln Extension: Historical Materials

Delay of irrigation for a few days during a critical part of the growing season can be expensive. A week's delay in supplying irrigation water to corn or grain sorghum can reduce potential yield more than 30 bushels per acre.

Several methods are available to help you schedule the right amount of water at the right time. One of these methods uses electrical resistance blocks discussed in this NebGuide.
