Multiple deliveries and long turnaround times on construction sites harm the environment disturb on-site productivity safety. The purpose of this paper is to investigate transport patterns material deliveries, including times. In order number transports times, data for 13 Swedish sites, which were collected with help booking systems, used. By comparing from cases, several observed: (i) very few...

This study presents a deep neural network (DNN)-based safety monitoring method. Nonstationary objects such as moving workers, heavy equipment, and pallets were detected, their trajectories tracked. Time-varying zones (SZs) of estimated based on trajectories, velocities, proceeding directions, formations. SZ violations are defined by set operations with sets points in the SZs object trajectories...

In the paper, through a case study of company from field forestry, an analysis product portfolio was carried out and position each defined within BCG (growth/share) matrix. As well as that, based on conducted SWOT analysis, company?s strengths, weaknesses, opportunities threats envi?ronment, were identified. The goal paper is to identify best way use financial resources define need introduce ne...

Printing companies are commonly SMEs with high flow of materials, which management could be significantly improved through the digitalization. In this study we propose a smart Warehouse 4.0 solution by using QR code, open-source software tools for machine vision and conventional surveillance equipment. Although there have been concerns regarding usage in logistics, it has shown to suitable part...

The objective of this study was to evaluate processing methods for frozen beef subprimals; the effects of freezing and thawing rates on tenderness, sensory properties, and retail display were evaluated. There were 6 treatments: fresh, never frozen 14 d wet aged (14D); fresh, never frozen 21 d wet aged (21D); blast frozen-fast thawed (BF); blast frozen-slow thawed (BS); conventionally frozen-fas...

This paper presents a simulation model that has been developed to analyse how the application of Radio Frequency Identification technology (RFID) affects material handling activities in a retail distribution centre. The simulation model handles both stochastic and dynamic behaviours, and describes how the receiving, picking and shipping activities will behave and perform over time when RFID tag...
