School Timetable
A school timetable is a calendar that coordinates students and teachers within the classrooms and time periods of the school day. Other factors include the class subjects and the type of classrooms available (for example, science laboratories). Since the 1970s, researchers in operations research and management science have developed computerized solutions for the school timetable problem (STP). Description and purpose of a school timetable A school timetable consists of a list of the complete set of offered courses, as well as the time and place of each course offered. The purposes of the school timetable are to inform teachers when and where they teach each course, and to enable students to enroll in a subset of courses without schedule conflicts. Also available as .pdfHoshino & Fabris/ref> History Prior to the introduction of operations research and management science methodologies, school timetables had to be generated by hand.

Classroom
A classroom or schoolroom is a learning space in which both children and adults learn. Classrooms are found in educational institutions of all kinds, ranging from preschools to universities, and may also be found in other places where education or training is provided, such as corporations and religious and humanitarian organizations. The classroom provides a space where learning can take place uninterrupted by outside distractions. Types of classroom In the United States In elementary schools (from Kindergarten through 5th grade), classrooms can have a whole group of 18 to 30 students (in some cases these numbers may differ) and one, two, or even three teachers. When there are two teachers in a classroom, one is the lead teacher and the other one is the associate. Or the second teacher might be a special education teacher. There may be a third teacher in the back watching and taking notes. In lower elementary the classrooms are set up slightly different from upper elementar ...

Period (school)
A school period is a block of time allocated for lessons/classes in schools and colleges. They typically last between 30 and 120 minutes, with around 3-10 periods per school day. However, especially in higher education, there can be many more. Educators determine the number and length of these periods, and may even regulate how each period will be used. One common example of this practice is to designate at least one compulsory period a day for physical education. A school bell The ringing of a school bell announces important times to a school's students and staff, such as marking the beginnings and ends of the school day, class period, and breaks. In some schools it may take the form of a physical bell, usually e ... is often used to indicate when a period begins and ends.

Operations Research
Operations research ( en-GB, operational research) (U.S. Air Force Specialty Code: Operations Analysis), often shortened to the initialism OR, is a discipline that deals with the development and application of analytical methods to improve decision-making. It is considered to be a subfield of mathematical sciences. The term management science is occasionally used as a synonym. Employing techniques from other mathematical sciences, such as modeling, statistics, and optimization, operations research arrives at optimal or near-optimal solutions to decision-making problems. Because of its emphasis on practical applications, operations research has overlap with many other disciplines, notably industrial engineering. Operations research is often concerned with determining the extreme values of some real-world objective: the maximum (of profit, performance, or yield) or minimum (of loss, risk, or cost). Originating in military efforts before World War II, its techniques have grown to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Management Science
Management science (or managerial science) is a wide and interdisciplinary study of solving complex problems and making strategic decisions as it pertains to institutions, corporations, governments and other types of organizational entities. It is closely related to management, economics, business, engineering, management consulting, and other fields. It uses various scientific research-based principles, strategies, and analytical methods including mathematical modeling, statistics and numerical algorithms and aims to improve an organization's ability to enact rational and accurate management decisions by arriving at optimal or near optimal solutions to complex decision problems. Management science looks to help businesses achieve goals using a number of scientific methods. The field was initially an outgrowth of applied mathematics, where early challenges were problems relating to the optimization of systems which could be modeled linearly, i.e., determining the optima (Maxima an ...

Gunther Schmidt
Gunther Schmidt (born 1939, Rüdersdorf) is a German mathematician who works also in informatics. Life Schmidt began studying Mathematics in 1957 at Göttingen University. His academic teachers were in particular Kurt Reidemeister, Wilhelm Klingenberg and Karl Stein. In 1960 he transferred to Ludwig-Maximilians-Universität München where he studied functions of several complex variables with Karl Stein. Schmidt wrote a thesis on analytic continuation of such functions. In 1962 Schmidt began work at TU München with students of Robert Sauer, in the beginning in labs and tutorials, later in mentoring and administration. Schmidt's interests turned toward programming when he collaborated with Hans Langmaack on rewriting and the braid group in 1969. Friedrich L. Bauer and Klaus Samelson were establishing software engineering at the university and Schmidt joined their group in 1974. In 1977 he submitted his Habilitation "Programs as partial graphs". He became a professor in 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Logical Matrix
A logical matrix, binary matrix, relation matrix, Boolean matrix, or (0, 1) matrix is a matrix with entries from the Boolean domain Such a matrix can be used to represent a binary relation between a pair of finite sets. Matrix representation of a relation If ''R'' is a binary relation between the finite indexed sets ''X'' and ''Y'' (so ), then ''R'' can be represented by the logical matrix ''M'' whose row and column indices index the elements of ''X'' and ''Y'', respectively, such that the entries of ''M'' are defined by :M_ = \begin 1 & (x_i, y_j) \in R, \\ 0 & (x_i, y_j) \not\in R. \end In order to designate the row and column numbers of the matrix, the sets ''X'' and ''Y'' are indexed with positive integers: ''i'' ranges from 1 to the cardinality (size) of ''X'', and ''j'' ranges from 1 to the cardinality of ''Y''. See the entry on indexed sets for more detail. Example The binary relation ''R'' on the set is defined so that ''aRb'' holds if and only if ''a'' ...

Hypergraph
In mathematics, a hypergraph is a generalization of a graph in which an edge can join any number of vertices. In contrast, in an ordinary graph, an edge connects exactly two vertices. Formally, an undirected hypergraph H is a pair H = (X,E) where X is a set of elements called ''nodes'' or ''vertices'', and E is a set of non-empty subsets of X called ''hyperedges'' or ''edges''. Therefore, E is a subset of \mathcal(X) \setminus\, where \mathcal(X) is the power set of X. The size of the vertex set is called the ''order of the hypergraph'', and the size of edges set is the ''size of the hypergraph''. A directed hypergraph differs in that its hyperedges are not sets, but ordered pairs of subsets of X, with each pair's first and second entries constituting the tail and head of the hyperedge respectively. While graph edges connect only 2 nodes, hyperedges connect an arbitrary number of nodes. However, it is often desirable to study hypergraphs where all hyperedges have the same card ...

Constraint Satisfaction Problem
Constraint satisfaction problems (CSPs) are mathematical questions defined as a set of objects whose state must satisfy a number of constraints or limitations. CSPs represent the entities in a problem as a homogeneous collection of finite constraints over variables, which is solved by constraint satisfaction methods. CSPs are the subject of research in both artificial intelligence and operations research, since the regularity in their formulation provides a common basis to analyze and solve problems of many seemingly unrelated families. CSPs often exhibit high complexity, requiring a combination of heuristics and combinatorial search methods to be solved in a reasonable time. Constraint programming (CP) is the field of research that specifically focuses on tackling these kinds of problems. Additionally, Boolean satisfiability problem (SAT), the satisfiability modulo theories (SMT), mixed integer programming (MIP) and answer set programming (ASP) are all fields of research focusin ...

Block Scheduling
Block scheduling or blocking is a type of academic scheduling used in schools in the American K-12 system, in which each pupil has fewer classes per day. It is more common in middle and high schools than in primary schools. Each class is scheduled for a longer period of time than normal (e.g. 90 minutes instead of 50). In one form of block scheduling, a single class will meet every day for a number of days, after which another class will take its place. In another form, daily classes rotate through a changing daily cycle. Blocks offer more concentrated experiences of subjects, with fewer, usually half as many if going through a schedule transfer, classes daily. Description Under a traditional American schedule, pupils in a high school will study six or seven subjects a day for 45 to 50 minutes for each day of the week for a semester. There will be two semesters in the year so 14 subjects could be studied. Some pupils will not study all seven subjects. There was great variety a ...

Modular Scheduling
Modular scheduling (also known as flex scheduling, flexible modular scheduling, or modular flex scheduling) is a system of timetabling in certain high schools in the United States. History Modular scheduling was developed by schools such as the Kent State University School in the 1960s. About 15% of American high schools implemented it in the 1960s, but since the 1970s, the practice has waned in popularity as schools have implemented block scheduling instead. Characteristics Each module, or "mod" (as it known colloquially), is either a 20 or 40-minute period used for classes or independent study time. This allows freedom in scheduling as classes can be 40, 60, or 80 minutes long, as needed for one-to one, small group, large group, and laboratory instruction. Classes are taught in a similar format to many universities; students meet a large group lecture once per week and have small group recitations throughout the week. An average student has at least one or two full open mods (fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
