正如前面的文章[I]所指出的，基本上有两种类型的布局软件包，它们更多地关注使用优化算法产生接近最佳的布局，而不是数据输入和解决方案显示级别的界面，以及其他主要关注用户界面，很少强调产生高质量的布局。在过去的十年中，人们尝试开发介于两个极端之间的软件包。螺旋就是这样一种尝试。这是一个商业上可用的程序，开发（单层）块布局给定的建筑尺寸信息，一些基本的部门信息，和部门之间的相互作用指定为每个时间段的旅行次数。然后，该程序使用几种基于图论的算法之一来开发块布局。SPIRAL中的数据输入可以通过交互方式或ASCII数据文件完成。在输入建筑物和部门信息后（例如，面积、长宽比）以及交互信息，用户必须让程序构造平面六边形邻接图。用户必须输入三种算法设置（其中一种确定使用双向还是三向改进算法）。ObviSPIRAL有几个很好的功能，包括通过点击块布局中的部门来编辑部门信息的能力，允许用户控制部门形状，以防止形成长而窄的部门布局，连续或离散的部门表示等。98或NT操作系统应该感到舒适的接口在数据输入和解决方案显示水平的螺旋。该程序不允许用户将部门固定在指定的位置或防止将部门分配到建筑物内的禁区。总的来说，SPIRAL软件是一个有用的布局生成、操作和评估工具。构造器会发现它是一个有吸引力的块布局开发工具，用于说明基本的布局和图论概念。从业者还将发现它是一个有用的工具，可以生成替代布局，评估它们并相对轻松地执行敏感性分析。SPIRAL软件可从Marc Goetschalckx，4031 Bradbury Drive，Marietta，GA 30062-6165（电话：770565-3370）。
As noted in an earlier article [I], there are basically two types of layout software packages those that focus more on producing near-optimal layouts using optimization algorithms and less on interface at the data entry and solution display levels, and others that focus heavily on user interface with very little emphasis on producing good quality layouts. In the past decade, there have been attempts to develop software packages that are between the two extremes. SPIRAL is one such attempt. It is a commercially available program that develops (singlefloor) block layouts given building dimension information, some basic departmental information, and the interaction between departments specified as number of trips per time period. The program then develops a block layout using one of several graph theory-based algorithms. Data input in SPIRAL can be done interactively or via ASCII data files. After entering the building and departmental information (e-g., area, length to width ratio) as well as the interaction information, the user must have the program construct a planar hexagonal adjacency graph. There are three algorithm settings (one of which determines whether a two-way or three-way improvement algorithm is to be used) that the user must enter. ObviSPIRAL has several nice features including the ability to edit departmental information by clicking on a department in the block layout, allowing the user to control departmental shapes so as to prevent formation of layouts with long and narrow departments, continuous or discrete representation of departments, etc. Users familiar , with the Windows 95, 98 or NT operating system should feel comfortable with the interface at the data entry and solution display levels in SPIRAL. The program does not allow the user to fix departments in specified locations or prevent allocation of departments to forbidden areas within a building. Overall, the SPIRAL software is a useful layout generation, manipulation and evaluation tool. Tnstructors will find it an attractive block layout development tool to illustrate basic layout and graph theory concepts. Practitioners will also find it a useful tool to generate alternative layouts, evaluate them and perform sensitivity analysis with relative ease.
