Supply Analysis

A system for designing timber management strategies which considers the location, construction timing, and standards of road networks is presented. The system allows the effects of alternative road networks on economic wood supplies and timber management strategies to be assessed. A geographic information system is used to update stand attributes in response to alternative road networks, prior to analysis using a linear-programming-based forest planning model. A case study illustrating the planning system is briefly reviewed and instructions for obtaining system software are provided. Key Words: timber management planning, geographic information system, spatial analysis, road network design, linear programming, wood supply analysis.

Road lighting information is an important record in road network databases. It has been frequently observed that such data are either missing or not updated due to the high data collection cost using traditional methods. This paper presents a new methodology for identifying and (or) resolving missing and conflicting road lighting data in road network databases. The methodology is based on: (i) integrating the single-line road network (SLRN) in a geographic information system format with a road network database and (ii) integrating the SLRN with a collision database. Missing and conflicting lighting data are resolved using a semi-automatic method for extracting streetlight pole information. The integrated system can also identify inconsistencies related to short segments and segments with mixed illumination characteristics. Inconsistencies in the traffic volume database were also examined and the effect of data inconsistency on safety performance functions was evaluated. The proposed methodology represents an inexpensive, efficient tool for improving the quality of road network databases and associated road safety analysis.

Manufacturing, storage, and transportation processes are typically facilitated by pallets, containers, and other reusable transport items (RTIs) designed to guarantee many cycles along a lifespan of several years. As a consequence, both supply and reverse transportation of RTIs need to be managed to avoid stockout along the supply chain and the unsustainable production of new tools from virgin materials. This paper focuses on the business of pallet management by analyzing the transport operations of a pallet pooling network serving a large-scale nationwide retailer. The pooler is responsible for supplying, collecting, and refurbishing pallets. The combination of the pooler’s management strategies with different retailer network configurations results in different pooling scenarios, which are assessed and compared in this paper through a what-if analysis. The logistical and environmental impacts generated by the pallet distribution activities are quantified per each scenario through a tailored software incorporating Geographic Information System (GIS) and routing functionalities. Findings from this analysis suggest how to reduce vehicle distance traveled (vehicles-km) by 65% and pollutant emissions by 60% by combining network infrastructures and pooling management strategies—identifying an empirical best practice for managers of pallet businesses.

Goals And Objectives

This research solves the problem of navigation network construction for panoramic survey points inside courtyards without using road network information. The described method of navigation network construction takes into account a number of geometric conditions that detecting and identifying the regularities of the decisive routing rules construction. An algorithm for constructing links between panoramic shooting points, based on the surrounding area and linear objects territory information, is presented. An intelligent agent of geographic information system has been developed that executes this task based on the proposed decision rules. The goals and objectives of the research are presented, input data array to solve the problem is considered, the formulation of geometric conditions, structure and object implementation of the algorithm are set out in this work. The task is viewed in terms of the perspective of graph theory, implemented in the DBMS PostgreSQL and illustrated in the QGIS geographic information system.

ABSTRACT Geographic Information System (GIS) is an indispensable software tool in forest planning. In forestry transportation, GIS can manage the data on the road network and solve some problems in transportation, such as route planning. Therefore, the aim of this study was to determine the pattern of the road network and define transport routes using GIS technology. The present research was conducted in a forestry company in the state of Minas Gerais, Brazil. The criteria used to classify the pattern of forest roads were horizontal and vertical geometry, and pavement type. In order to determine transport routes, a data Analysis Model Network was created in ArcGIS using an Extension Network Analyst, allowing finding a route shorter in distance and faster. The results showed a predominance of horizontal geometry classes average (3) and bad (4), indicating presence of winding roads. In the case of vertical geometry criterion, the class of highly mountainous relief (4) possessed the greatest extent of roads. Regarding the type of pavement, the occurrence of secondary coating was higher (75%), followed by primary coating (20%) and asphalt pavement (5%). The best route was the one that allowed the transport vehicle travel in a higher specific speed as a function of road pattern found in the study.
