Linear optimization model for fish processing production planning
… maximized subject to raw material requirements, machine time requirements, orders, and contracts. The model was tested and validated using real data from a typical processing day at a vertically integrated fishery in Iceland. Keywords: Linear programming, Product mix, Production planning, Fish …

Constraint-based facilities planning
… facilities much earlier than their lifetime. A model was built to assess the impact of manufacturing parameters on the effectiveness of the layout and the material handling system. A relationship was developed between variations in production oriented parameters and its impact on the …

Improving an IBM type 650 digital computer operation by programming the inverse of a partitioned matrix as used in the analysis of rectangular rigid frames
… for the IBM Type 650 Computer are entirely too time consuming when the matrix coefficients and program instructions exceed the storage capacity of the computer drum. The method described in this paper involves the solution of the problem by the inversion of a partitioned matrix originally …

Reducing the costs of bounded-exhaustive testing
… The costs of bounded-exhaustive testing include machine time for test generation and execution (which translates into human time waitingfor these results) and human time for inspection of results. We propose and evaluate three orthogonal techniques that reduce these costs. Sparse Test Generation …

Automated Loading and Unloading of the Stratasys FDM 1600 Rapid Prototyping System
… build jobs are still manually activated one at a time. The result is non-productive machine time whenever an operator is not at hand to make a job changeover. A low-cost auxiliary system, named Continuous Layered Manufacturing (CLM), has been developed to automatically load and unload the FDM 1600 …

Some aspects of stratified flow in closed conduits
… equations by elimination. Less than two minutes machine time was required for a 39 by 39 matrix. Experimental results demonstrated fairly well the energy loss concept in surge wave considerations. The major energy loss at the wave front was assumed to be the expansion loss of the lower layer. The …

Comprehensive Calculation-Based Imrt Qa Using R&V Data, Treatment Records, and A Second Treatment Planning System
… QA measurements are labor intensive and consume machine time. Calculation-based IMRT QA methods typically are not comprehensive. We have developed a comprehensive calculation-based IMRT QA method to detect uncertainties introduced by the initial dose calculation, the data transfer through the …

Reducing Curvature in Complex Tool Paths by Deviating from CAM-Produced Tool Paths Within a Tolerance Band
… for complex parts to achieve shorter machining times resulting in higher production rates. In the research sample cases, the algorithm decreased machining times by 1% to 9% for design-induced sections of high curvature and by 16% to 75% for CAM induced ripples using high path tolerances. …
