We are given n jobs 1, 2, . . . n, and a release time r. Each job i has duration t(i) > 0 and deadline d(i). A schedule s defines, for each job i, a start time s(i) ≥ r so that for any two distinct jobs i and j the intervals [s(i), s[i] + t(i)] and [s(j), s(j) + t(j)] do not overlap (one finishes no later than the other starts). The lateness l(i) of job i in schedule s is the amount of time by ...

Abstract The aim of this paper is to analyze Anne Louise Germaine de Staël’s novel Corinne ou l’Italie (1807) from the point view cultural studies and visual studies, shed a light on attempt at promoting construction modern Italian national identity, founded arts. article examines how participation in nation-building was half linked her prejudices upon lateness process civilization Northern Eur...

Flexible manufacturing system (FMS) readily addresses the dynamic needs of the customers in terms of variety and quality. At present, there is a need to produce a wide range of quality products in limited time span. On-time delivery of customers’ orders is critical in make-to-order (MTO) manufacturing systems. The completion time of the orders depends on several factors including arrival rate, ...

This paper presents an algorithm for oo-line scheduling of communicating tasks with precedence and exclusion constraints in distributed hard real-time systems. Tasks are assumed to communicate via message passing based on a time-bounded communication paradigm such as the real-time channel 1]. The algorithm uses a branch-and-bound (B&B) technique to search for an optimal task schedule by minimiz...

ÐThis paper presents an algorithm for off-line scheduling of communicating tasks with precedence and exclusion constraints in distributed hard real-time systems. Tasks are assumed to communicate via message passing based on a time-bounded communication paradigm, such as the real-time channel [1]. The algorithm uses a branch-and-bound (B&B) technique to search for a task schedule by minimizing m...

In this study, we focus on the packet scheduling problem especially with respect to the steering overhead of the steered antenna system. Our scheduling problem is investigated with a generic network model, while the objective of the problem is the throughput metric, which is the essentially metric in wireless systems. We prove the tractability of the problem by proposing an optimal covering alg...

A common industrial operation is a dual resource constrained job shop where: (a) the objective is to minimize Lmax, the maximum job lateness; (b) machines are organized into groups; and (c) each worker is assigned to a specific machine group. Because this problem is NP-hard, finding optimal solutions by enumeration is impractical. This paper details a procedure to compute a lower bound on Lmax ...

In this paper we consider a combined production-transportation problem, where n jobs have to be processed on a single machine at a production site before they are delivered to a customer. At the production stage, for each job a release date is given; at the transportation stage, job delivery should be completed not later than a given due date. The transportation is done by m identical vehicles ...

Directly influenced by Colin Rowe’s essay “Mathematics of the Ideal Villa” (1947) and Warburgian art historical tradition, John Hejduk’s nine-square grid studio exercise had an ambiguous relation to instrumentality architectural history. When was copied in many architecture schools around world as a first-year project, initiating novice student realm composition, pedagogical interpretation its ...
