The Effect of Uncertain End-of-Life Product Quality and Consumer Incentives on Partial Disassembly Sequencing in Value Recovery Operations
… is motivated by the rising importance of value recovery and sustainability to manufacturers. Extended Producer Responsibility (EPR) and Product Stewardship (PS) policies are, globally, changing the way products are treated during their use-life and EoL. Each new policy places a greater …

Evaluation of a direct processing system for converting no. 3 grade red oak logs into rough dimension parts
… yields of green dimension parts and dollar value recovery from No.3 grade red oak logs by the direct processing system were estimated. A combination method of actual log sawing and simulated cutting was used to obtain the dimension yields. Two sawing patterns (live-sawing and …

Essay on the Persistence of Corporate Diversification Discount after Merger and Acquisition Transactions and Essay on the Capital Structure Properties of Real Estate Investment Trusts (REITs)
… weak evidence that leverage, by itself, creates value. Nevertheless, I find strong evidence that during financial crisis debt-restricted REITs perform better than non-restricted ones. Also I find evidence that lends support to the pecking order story of leverage. I conclude that REITs managers …

Optimization of edging and trimming operations for red oak lumber
… The main objective was to evaluate how lumber value recovered by actual hardwood operations compare with the maximum value obtainable through the optimization of edging and trimming. An optimization procedure was developed involving the use of an iterative computer program for finding optimum …

The Performance of Real Estate Investment Strategy Across Multiple Cycles: A Comparison of Core and Non-Core Strategies Based on A New Dataset and Industry Interviews
… professionals point to a transition from falling values in 2023 to value recovery in 2024. The interviews also signal the short-term opportunities for Core/Core-plus strategies in the forthcoming lower-rate environment, as inflation eases. The thesis also underscores the importance of aligning …

Case Studies in Value Improvement in Hardwood Timber Harvesting Operations in the southern Appalachians
… case studies focused on harvesting operation value improvement: (1) A productivity study was carried out on a new cable logging operation near Pikeville, Kentucky to document the effect of professional training on production efficiency. The crew received one full week of professional training. …

The potential for short length lumber in the furniture and cabinet industries
… used to evaluate opportunities for improving the value of a piece of lumber by trimming a lower grade, longer length piece to obtain a shorter, higher grade board. The defect data indicated that wane makes up a slightly higher percentage of the total defect area for short boards than for long …

A feasibility study on using CT image analysis for hardwood log inspection
To fully optimize the value of material produced from a log requires information about the log's internal defects prior to log breakdown. Studies have shown that a 7 to 21 percent improvement in log value recovery can be achieved if the location and identity of internal defects are known. Recent …

A simulation and empirical study of cross-laminated timber from waney SA Pine timber
… of conversion of logs to sawn boards, or volume recovery, is consequently one of the main performance indicators for sawmills. The first objective of this study was to quantify the improvement in volume recovery possible when cross-laminated timber (CLT) component manufacturing with increased …
