We describe the application of simulation and statistical analysis to the problem of optimization of palletization in a production job shop. These analyses enabled management responsible for the production of this job shop to optimize the number of pallets, the size (carrying capacity) of the pallets, the associated workin-process levels, and policy regarding level of safetystock kept on hand a...

This article presents the use of the synchrosqueezing transform (SST) for the timefrequency analysis of shock and vibration measurements. The time-frequency resolution properties of SST is demonstrated by analyzing acceleration measurements from pallets dropped from heights and vibration of pallets acquired in controlled laboratory settings. The article presents results that indicate that SST, ...

There exist a number of mathematical problems in the literature concerning warehouse storage optimization. However, to the best of our knowledge the problem of finding optimal slot sizes in pallet rack system minimizing the occupied storage space is not studied. More precisely, the problem is to optimally choose k ofm pallet racks with pallets in a warehouse, find optimal slot sizes in pallet r...

Wood packaging represents a pathway for the introduction and spread of pests. In March 2002, the Food and Agriculture Organization (F.A.O.) issued some regulations describing globally approved phytosanitary measures that significantly reduce the risk provoked by most of pests. The main purpose of this work is to describe the disinfesting system of pallets through the microwaves treatment.

For a real world problem — transporting pallets between warehouses in order to guarantee sufficient supply for known and additional stochastic demand — we propose a solution approach via convex relaxation of an integer programming formulation, suitable for online optimization. The essential new element linking routing and inventory management is a convex piecewise linear cost function that is b...

A cell separation strategy capable of the systematic isolation and collection of moderate to large numbers (25-400) of single cells into a targeted microwell is demonstrated. An array of microfabricated, releasable, transparent micron-scale pedestals termed pallets and an array of microwells in poly(dimethylsiloxane) (PDMS) were mated to enable selective release and retrieval of individual cell...

High-quality pallets are easier to repair and last longer. To obtain the high-quality parts necessary to build durable pallets requires grading and sorting by an automated inspection system. Ultrasonic sensing was selected for this application because 1) it is relatively inexpensive; 2) it can penetrate and characterize internal features of wood specimens; and 3) its effectiveness has been demo...

Although aedine eggs are resistant to desiccation, little is known about this trait in Haemagogus species. In study, we assessed the desiccation resistance of Hg. spegazzinii eggs. The were collected using ovitraps over a period one week March 2020. positive pallets stored until experimentation and immersed solution water yeast for larval hatching subsequent species identification. emerged adul...
