Thesis (PhD (Logistics))--University of Stellenbosch, 2010.<br>ENGLISH ABSTRACT: Computerised sugarcane harvest scheduling decision support is an active fi eld of research which ties in closely with the broader problem of automating and streamlining the various activities in the sugar supply chain. In this dissertation, the problem of providing decision support with respect to sugarcane harvesting decisions is defined within a number of contexts, each representing a typical kind of organisation of sugarcane farmers into a cohesive decision making unit with its speci fic requirements and l

Abstract:

A computerized system for planning timber harvest to maximize habitat quality over time for a specified group of wildlife species was developed for upland oak forests of the Eastern United States. This system, called WILDWOOD for WILDiife/WOOD optimization system, is designed to run on a microcomputer. It utilizes a widely available database management system called PCFile III, Version 4, a forest growth and yield simulator adapted from work by Dale (1972), and a program developed by the author. The system utilizes 43 species-specific habitat value models developed by the author and others. Ti

Abstract:

<p>This thesis is concerned with structure exploitation and the design of algorithms for solving large-scale harvest scheduling problems. We discover that the harvest scheduling problem involving area constraints possesses a network structure. In Model I-Form 1, the network constraints form a separable block diagonal structure, which permits one to solve for the decision variables belonging to each individual area constraints as independent knapsack problems. In Model II-Form 1, the network constraints constitute a longest path problem, and a Longest Path Algorithm is developed to solve this p

Abstract:

This thesis reports on enhancements of two planning method components aimed at improving management and planning of forest plantations in the tropics. The two modular planning models subjected to detailed study are growth and yield modelling and harvest scheduling. A case study relating to Caribbean pine in Fiji is used to demonstrate the refined capability. Growth and yield modelling has been improved by applying modern statistical and computer techniques to solve non-linear equations that describe growth of stands appropriately. Further improvements have been achieved by developing diamete

Abstract:

Thesis (MSc)--Stellenbosch University, 2015.<br>ENGLISH ABSTRACT: Profitability in the export driven South African blueberry industry is dependent on early spring harvests. The George region in the Western Cape accumulates too few chill-units to release buds of some southern highbush (SHB) blueberry cultivars from endodormancy. This causes problems like delayed budbreak and extended harvests. Growers of other temperate fruit crops are also affected by these problems and chemical rest breaking agents (RBAs) are applied in orchards in an attempt to overcome these.

Abstract:

In the states of Tabasco and Chiapas, Mexico there is a lack of long-term harvest scheduling models that consider the effects of the harvest activities on the surrounding areas. Additionally, these problems are combinatorial in nature, which makes them hard to solve. Consequently, only harvest scheduling for small areas can be solved to optimality using traditional approaches such as integer programming (IP). In this study, a genetic algorithms (GA) model was used to generate multiple viable solutions for long-term spatially constrained problems on large areas with a great number of management

Abstract:

The problem of optimal land organization was approached via a general methodology to aggregate finely distinguished planning unit areas of an even-aged ponderosa pine forest in Northwestern Mexico. Factor analysis was applied to eighteen timber inventory variables to produce four independent and meaningful constructs that explained 87% of the total variable set’s variation. Next, each planning unit area was characterized by its factor scores and an Euclidean-metric based analysis was applied. The resultant Dendrograrn’s structure helped to define four levels of land aggregation that were evalu

Abstract:

To date, rechargeable Wireless Sensor Networks are of great interest because sensor nodes are able to harvest energy from their environment, e.g., solar and wind, and store the harvested energy in rechargeable batteries. In this thesis, we design three greedy heuristic algorithms, i.e., LS-rWSN, LSBCC, and LSDBS, to solve three proposed link scheduling problems in rWSNs, i.e., LSHUS, LSME-1, and LSME-2. Simulations on arbitrary networks show the merits and effectiveness of the proposed solutions.

Abstract:

This thesis describes the Operational Harvest Scheduling (OHS) problem and develops an algorithm that solves instances of the problem. The solution to an OHS problem is an Operational Harvest Schedule (OHS). An OHS: ² assigns forest harvesting crews to locations within a forest in the short-term (4-8 weeks); ² instructs crews to harvest specific log-types and allocates these log-types to customers; ² maximises profitability while meeting customer demand. The OHS problem is modelled as a Mixed Integer Linear Program (MILP). The formulation given in this thesis differs significantly from previou

Abstract:

The objective of this research was to develop, evaluate, and understand a new heuristic algorithm for solving the spatial harvest-scheduling problem. The new algorithm, indirect search, is a combination of a greedy heuristic and a neighborhood search. It was developed with the intention of quickly computing near-optimal solutions to large harvest-scheduling problems where harvest activities are treated as 0-1 variables. For this study, the algorithm solved two harvest-scheduling problems constrained by even-flow and two-period adjacency constraints: 1) a set of small tactical problems c

Abstract:

Including ecological objectives within strategic planning on forested lands is important because timber harvesting can reduce the value of these objectives. Harvesting is a valuable source of economic revenue, but changes the age-class structure of the forest, often significantly reducing the amount of late-seral stands. Late-seral stands help meet a wide variety of objectives, such as biodiversity, water quality, and, recreation. From an economic perspective, proper management of late-seral stands often is necessary to acquire "social license" for continued harvesting operations. Most

Abstract:

To protect non-timber resources such as wildlife, water quality and aesthetics, harvesting regulations have been introduced that limit opening size, and set minimum green-up times. Many constraints have been introduced to long-term, multiple-use forest planning problems. Proper scheduling of cut blocks for the large-scale integrated forest planning is important in order to produce the maximum amount of timber from the land base without violating the constraints. Also, these problems are difficult to solve due to the problem size and the constraint structure. These non-linear comb

Abstract:

This thesis addresses two major topics. First, impacts on timber supply and economics associated with sustained yield unit size are investigated. Partitioning the forest into sustained yield units is a complex task that involves assessing timber supply, allocation of cutting rights, and social, economic, and environmental impacts. There are numerous ways to vary the timing and intensity of harvests within individual drainages while still meeting the objectives of sustained yield. In this paper a spatial forest planning model is used to examine economic and environmental implications of v
