We consider an agricultural production problem, in which one must meet a known demand of crops while respecting ecologically-based production constraints. The problem is twofold: in order to meet the demand, one must determine the division of the available heterogeneous arable areas in plots and, for each plot, obtain an appropriate crop rotation schedule. Rotation plans must respect ecologically-based constraints such as the interdiction of certain crop successions, and the regular insertion of ...

Industrial production processes involving both lot-sizing and cutting stock problems are common in many industrial settings. However, they are usually treated in a separate way, which could lead to costly production plans. In this paper, a coupled mathematical model is formulated and a heuristic method based on Lagrangian relaxation is proposed. Computational results prove its effectiveness.

Penstemon seed often shows an inconsistent or a low germination percentage. Although most select cultivars are propagated by cuttings, for export to other countries, seed is preferred. Three experiments were conducted to determine if soaking seed in gibberellic acid (GA 3 ) would increase seed germination of Penstemon digitalis cv. Husker Red. GA 3 concentrations used were 0, 10, 50, 100, 200, and 500 mg·L −1 (first experiment); 0, 500, 1000, and 1500 mg·L −1 (second experiment); and 0, 500, and 1000 mg· ...

The problem of generating guillotine cutting patterns for a rectangular plate is studied and a type of structure is proposed for representing the solution of the problem, called and-or graph, which is commonly used in the Artificial Intelligence environment. To search the graph we combined two classical strategies: depth-first and hill-climbing. Further, some heuristics are considered and computational results are presented, relating their performance on examples from both literature as well as ...

This work consists of the study of a foundry which has only one furnace and several moulding machines producing a known demand of different types of items which can be made of different alloys. There are two important and linked decision levels in this foundry: (1) what alloys should be produced in the furnace in each period, and (2) the quantity of items to be produced in each moulding machine. Two different cases are highlighted here: a single alloy can produce all the items, and different alloys ...

Accurate simulations of plant development is an important component in crop simulation models and for use in managerial decisions, such as fertilizer applications or pest control. The three major environmental factors that control development in winter wheat (Triticum aestivum L.) are temperature, photoperiod, and vernalization. Results from a previous study showed that the prediction of several developmental stages from booting to physiological maturity were better with the Wang and Engel (WE) model ...

Vernalization is a process required for certain plant species to enter the reproductive stage through an exposure to low, nonfreezing temperatures. These plant species include some fall‐planted cereals, among them winter wheat ( Triticum aestivum L.). A three‐stage linear function is currently used in wheat simulation models to describe the developmental response to the duration of the vernalization treatment, expressed as effective vernalization days (VD). This function lacks generality because the ...

The prediction of leaf appearance rate (LAR) is an important part of many crop simulation models. Most wheat simulations models assume that LAR is affected by temperature and photoperiod. This assumption ignores the fact that seed reserves contribute to a greater LAR of the first two leaves and that the LAR of subsequent leaves decreases as a result of an increase in the distance that each leaf primordium must extend before it appears. The objective of this study was to develop a generalized LAR ...

Leaf-to-air water vapor pressure deficit (VPD) is an important environmental factor that can affect stomatal functioning in higher plants. The objective of this review is to provide an overview on the stomatal response to VPD in higher plants and the possible mechanisms that have been proposed to explain such response. There are conflicting results about whether stomata respond to VPD or not. Soil water stress and leaf position are factors that may affect the stomatal response to VPD and can help ...

In this work we consider a one-dimensional cutting stock problem in which the non-used material in the cutting patterns may be used in the future, if large enough. This feature introduces difficulties in comparing solutions of the cutting problem, for example, up to what extent a minimum leftover solution is the most interesting one when the leftover may be used. Some desirable characteristics of good solutions are defined and classical heuristic methods are modified, so that cutting patterns with ...
