Depot Modernisation Parel Wr

1. Modernization of Stores Depot at Carriage Repair Workshop,Lower Parel, Western Railway through Implementation ofIntelligent WarehousingwithAutomated Storage & Retrieval System (ASRS)

Jogendra Yadvendu

Dy.CMM-PL, WR

Warehousing did not get its due importance on the Indian Railways because;

Materials management was always considered an ancillary activity.

When ever a new Locomotive sheds or a carriage workshop was planned, provision for the warehousing was never given a thought.

It was always believed that once the workshop a locomotive shed comes up, warehousing for the material shall take care of itself.

In the name of a warehouse, a ramshackle godown or an old steam shed or an abandoned building wasprovided in the name of a stores depot.

This continues even today.

New Electric Locomotive workshop at Dhaboi with an area of>2.5 LakhSq.mhas a provision of only15 m X 100 m for the materials management including warehousing.

New CoachPOH workshop at BVP with an approximate area of 3 lakh sq. mhas a provision for 15mX 100 m for the warehousing purpose.

New Mahim Scrap Depot in WR has a provision of13000 sq.m consisting of 20 bins of 15m * 12 m each.

Why is all this happening and what is the solution ?

Is Materials Management department required in the railways ?

If the answer is yes, Why the above scenario ?

Reasons:

Lack of will and vision in the departmental officers.

We want to be Goody Goody.

Don't want to raise inconvenient questions.

Hum Santust Hain.

The result:

Warehousing as well as the supply chain management still pertains to the era of Stone Age.

Result: Archaic Procurement Rules.

Mismatched inventory

Spoilage and rusting of costly material

Block storage on the ground floor

Inundation of material during flooding, leaking roofs etc.

Presently Modernization means getting a forklift or a Truck from the Sr.DEE in a locomotive shed or Dy.CME in a workshop .

CarriageStores Depot at Lower Parel is the biggest Stores Depot on Western Railway.

Annual material issues value of Rs. 600 Million.

Accounts forapproximately 25 % of the annual issues on Western Railway.

Caters toCarriage Workshop &Divisional Consignees (29).

It stocks around 1200 stock items out of which 167 are safety, 257 are vital, 38 passenger amenity items .

LHB Coachis a new technology with many items being imported and limited indigenous vendors

Stores depots on the Indian Railways are housed in a dilapidated structures released from the old steam loco sheds or abandoned carriage depots.

Hence the structural strength as well as mechanizationis almost nil in the old stores depots.

In the estimate for new workshops or Diesel/Electric Loco Sheds, few godowns are provided in the name of stores depot without M&P & material handlingequipment.

The entire gamut of activities in the workshops have been mechanized with the inclusion of new technology.

The material storage , handling and transportation in a stores depots needs to be modernized so that instead of just acting as a warehouse , the storesbecome a part of the supply chain management and the production process.

Presently, they work more as godowns rather than modern warehouses.

Pragmatic mix of IW-ASRS, Drive in Pallet System, Selective Pallet System, conveyor systems etc.

Structurally strong building with adequate free height for vertical storage.

Adequate material handling equipments and transportation facilities such as platform trucks, forklifts , LMV, HMV .

RDBMS based IT application for purchase & Inventory management with adequate Hardware resources.

The payment terms must be conducive to the vendors so that working capital is not blocked and contractors are not in distress.

Decision regarding MB.

Bulk storage using block stacking can result in the minimum cost of storage since cube utilization is high and no storage medium is required, but material accessibility is low since only the top of the front stack is accessible and loads at bottom of a stack must not require support

Storage racks are used when support and/or material accessibility is required

Pallets are supported between load-supporting beams

Special attachments and decking can be used to make the racks capable of supporting other types of unit loads besides pallets (e.g., coils, drums, skids)

Can be used for:

Standard single-deep storage using a counterbalanced lift truck

Narrow-Aisle storage using a narrow-aisle lift truck

Deep-Reach greater than single-deep storage (typically double-deep storage

Loads are supported by rails attached to the upright beams

Lift trucks are driven between the uprights beams

Requires similar-width loads

Open at both ends, allowing access from both ends (FIFO)

Same as drive-through rack, except closed at one end, allowing entry from only one end (LIFO)

Loads are supported on an incline to enable gravity-based movement of the loads within the rack (via, e.g., a gravity roller conveyor)

Loaded at the higher end and unloaded at the lower end (FIFO)

Same as flow-through rack, except loaded and unloaded at the lower end and closed at the higher end (LIFO)

Only one mobile aisle is used to access several rows of racks

Location of the aisle is changed by sliding the rows of racks along guide rails in the floor

Typically found in library stacks

Loads are supported by cantilever "arms"

Used to store long loads (e.g., bar stock, pipes, lumber)

Similar to pallet racks, except the front upright beams and the front supporting beams are eliminated

Carousel consists of a set of vertically or horizontally revolving storage baskets or bins

Materials (and the storage medium) move to the operator, "part-to-man," for end-of-aisle picking

Each level of the carousel can rotate independently in a clockwise or counter-clockwise direction

Control ranges from manually activated push buttons to automated computer controlled systems

Provides an alternative to typical "man-to-part" AS/RS, where the S/R machine moves to the part

Consists of an integrated computer-controlled system that combines the storage medium, transport mechanism, and controls with various levels of automation for fast and accurate random storage of products and materials

Storage/retrieval (S/R) machine in an AS/RS operates in narrow aisle, serving rack slots on both sides of aisle; can travel in horizontal (along the aisle) and vertical (up and down a rack) directions at same time

Advantages: fewer material handlers, better material control (including security), and more efficient use of storage space

Disadvantages: high capital Investment.

Used to store/retrieve loads that are palletized or unitized and weigh over 500 lbs.

Stacking heights up to 130 ft. high, with most ranging from 60 to 85 ft. high; 5 to 6 ft. wide aisles; single- or double-deep storage racks

Used to store/retrieve small parts and tools that can be stored in a storage bin or drawer

End-of-aisle order picking and replenishment

Stacking heights range from 12 to 20 ft.; bin capacities range from 200 to 750 lbs.

Termed a "microload AS/RS" when used in assembly, kitting, and testing operations to deliver small containers of parts to individual workstations, where workstations are typically located on the sides of a pair of racks and the S/R machine operates between the racks to move containers to openings in the racks (storage lanes) located next to each station

Used for in-aisle picking; operator picks from shelves, bins, or drawers within the storage structure

Manual or automatic control

S/R machine is similar to an order picker or turret truck and can sometimes operate as an industrial truck when outside an aisle, except the S/R is guided along a rail when operating in an aisle

Working Capacity: 1500 Kg. loads at 100% duty cycle

End-of-Aisle Run-out Required: 15 ft.

Height Requirements: 12 ft. to 100 ft.

Fork Extractor Mechanism:

Construction: Precession fabricated steel

Load Capacity: 1500 Kg.

Load Support: Industrial Standard Forks

Extractor Drive: Patented ball screw and rotator with variable frequency drives, industrial gear reducers, and brake.

Crane Rail:

Floor mounted , Rail mounted .

Vertical & Horizontal Drives:

High performance sine-coded, pulse width modulated AC vector motor drives which generates an adjustable voltage/ frequency three phase output for complete speed control.

Automatic stall prevention and voltage boost prevents nuisance tripping during load or line side transient conditions.

The drives will not induce any voltage or distortion back into the utility line and maintains a displacement power factor of not less than 0.98 throughout its speed range.

Communication:

Infrared Modem

S/R Machine Controls:

Electrical Components : IEEE code compliance throughout. IEEE rated enclosure, sensors, and wiring. Panel-mounted diagnostic indicator lights. Panel-mounted maintenance controls.

Logistics and Positioning : Onboard programmable controller A-B SLC-500 communication by infrared modem. Steel code bar, optical address readers. Fine positioning, motor-mounted resolvers with 1/16'' accuracy or 1 deg. Accurate positioning on start-up.

Safeguards:

Front and rear aisle-obstruction detectors. Onboard and off-board emergency stops. Load and centering sensors and interlocks.

Rack Structure:

Virtually any post and beam (conventional) existing or new racks capable of safely bearing the pallet loads (pushback and flow rack). Continuity of vertical shelf distance from floor not required. Common depth dimension recommended, but differing depths can often be accommodated. Racks must be attached to the floor but no shimming is needed except with extreme floor conditions.

Maximum Height: 100 ft.

Pallets:

Any two or four way pallet capable of being used.

Parel workshop has one of the smallestfootprint to Coach POH ratio.

Located in the heart ofMetropolitan city-Mumbai with costly land where lateral expansion is not a n option.
