ILOG Optimization Products Reduce Production Time From 17 Hours to Two


ILOG Optimizes Production And Planning Process at Hansol Paper

ILOG® (NASDAQ: ILOG; Euronext: ILO, ISIN: FR0004042364), a leading supplier of enterprise-class software components and services, today announced that Hansol Paper, one of the leading paper manufacturing companies in South Korea, has selected ILOG optimization software to streamline its complex paper planning and production processes, including managing inventory requirements, resulting in a more efficient overall process that has reduced production time from 17 hours to less than two hours.

In addition to reducing production time, ILOG optimization software has improved strategic decision-making, shortened sales cycles and reduced waste and other costs associated with Hansol’s production process.

Hansol is one of Asia’s leading newsprint paper manufacturers, producing 1.3 million tons of paper annually. In addition to being well established domestically, the company sells worldwide to organizations like the Los Angeles Times Corporation.

In order to utilize the least amount of paper and achieve maximum profit, Hansol created the “Hansol Integrated Production Scheduling System” based on a combination of three ILOG products - ILOG CPLEX®, ILOG Solver™ and ILOG Scheduler™. Hansol uses the combined solution to more effectively manage the planning and production of its highly complex manufacturing process, which involves multiple constraints that control factors such as determining the correct amount of pulp to purchase, minimizing the utilization of paper cutting machines, and reducing paper-type changes, preventing over-production or under-production during the cutting process, and decreasing the loss of paper during trimming.

"Hansol is committed to being a world-leading, environmentally-friendly paper manufacturing company. We believe superior technology from vendors such as ILOG will help us achieve the goal,” said S.K. Kim, senior manager of Hansol Paper Co Ltd. "By using ILOG optimization software, we are able to reduce paper waste yet still deliver the highest quality products to our customers."

ILOG optimization products are used in each phase of Hansol’s multi-stage production scheduling process, which includes a three month sales planning cycle, a one month production scheduling cycle, a cutting process that divides large jumbo-rolls of paper into several smaller optimally sized rolls, and finally a scheduling stage in which the smaller rolls are divided by sheet cutters in a process that considers load balance and other complex constraints.

Im Focus: Novel light sources made of 2D materials

Physicists from the University of Würzburg have designed a light source that emits photon pairs. Two-photon sources are particularly well suited for tap-proof data encryption. The experiment's key ingredients: a semiconductor crystal and some sticky tape.

So-called monolayers are at the heart of the research activities. These "super materials" (as the prestigious science magazine "Nature" puts it) have been...

Im Focus: Etching Microstructures with Lasers

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.

This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Im Focus: Light-driven atomic rotations excite magnetic waves

Terahertz excitation of selected crystal vibrations leads to an effective magnetic field that drives coherent spin motion

Controlling functional properties by light is one of the grand goals in modern condensed matter physics and materials science. A new study now demonstrates how...

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.

"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
